[@rosamy2017]

I have a material science degree and I’ve been a chemistry nerd my whole life and this is the best explanation I’ve ever seen of this phenomenon. The way I intuit it is that boiling is an endothermic process, meaning that the system pays with heat in order to change. You can pay the water with heat to make it boil, or you can depressurize the water and force it to pay its own heat as it is forced to boil.

[@randomsandwichian]

So in a nutshell, as best as I can put it: At our current atmospheric pressure, water needs more energy via boiling to become vapor. By decreasing the pressure it is in (like in the syringe, that amount of air and water is spread over a larger spatial area, hence the pressure dropping), less if not no energy is required to cause the change in state because of the available energy already in the water.

[@rosamy2017]

@@randomsandwichian It’s an equilibrium dependent on thermal energy, gibbs free energy, and pressure. There’s an equilibrium vapor pressure for every liquid at every temperature at which no more evaporation will occur. Technically more evaporation is always taking place, but condensation is happening at the same rate. Increase the temperature and the evaporation rate will become faster than condensation. Increase the pressure and condensation rate will become faster than evaporation. Until, in both cases, the vapor pressure once again reaches the equilibrium vapor pressure, and then both processes will be equal again.

Boiling occurs when the vapor pressure (the pressure at which the liquid is launching molecules into the air) becomes equal to the outside pressure. So in other words, the outside gas no longer has the pressure to squeeze and prevent the liquid from turning into gas, so they become the same phase. One way to boil a liquid is by increasing its temperature, and by extension vapor pressure. Another one is to simply decrease the outside pressure, and make them equal that way. Hope this helps!

I am a professional HVAC technician (heating, ventilation, air conditioning) and I just want to say you perfectly explained how air conditioners and refrigeration works. pressure and boiling points are directly tied together. when you raise/lower the pressure of a liquid, you raise/lower its boiling point. in an a/c or refrigerator, we take high pressure liquid refrigerant and pump it through a metering orifice, which is basically like holding your thumb over the end of a garden hose. After passing through the metering device, the refrigerant is now a much lower pressure, and it will boil at room temperature, which is how it absorbs heat from your house. the fan blows air across loops of pipe that the depressurized refrigerant is pumping through causing it to boil as it goes through the loops, absorbing the heat in the process. Then it goes to the outside unit to re-pressurize in order to raise the boiling point, which causes the now-gas refrigerant to condense back into a high-pressure liquid, dumping the heat it absorbed into the outside air in the process of it's change of state. It's a constant loop of manipulating the boiling point by changing the pressure. high boiling point to dump heat and low boiling point to absorb heat.

a simple and ideal vapor-compression cycle is composed of four processes: 1-2 compression in a compressor 2-3 heat rejection in a condenser 3-4 throttling in an expansion valve 4-1 heat absorption in an evaporator inside the tubes there is a refrigerant. the refrigerant starts by being compressed in the compressor and thus it heats up. then, it rejects heat to its surroundings through the condenser and leaves the condenser as a liquid. after that, it is throttled so it reaches the evaporator pressure by passing it through an expansion valve or a capillary tube (the principle the video shows). this also causes the refrigerant to cool down. finally, the refrigerant reaches the evaporator where it "sucks" the heat from the fridge so that it gains the necessary energy in order to evaporate back to a gas. this gas goes to the compressor and the cycle repeats itself. hope this helps.👍🏻

This phenomenon is why carbonated drinks are better cold. So this video is just about the misconception of the boiling phenomenon. Boiling is any time a liquid goes to a gas and it depends on the atmospheric pressure surrounding the liquid, called the vapor pressure. Like he said, boiling depends on the energy of the liquid, specifically if it has enough energy to become gas in the space above the liquid, so if you lower the psi, suddenly the lower-temperature molecules have enough energy to escape the liquid state. Think of it like an invisible hand pressing down on the liquid to keep the molecules from turning into vapor, which they want to do but can't because of that atmospheric pressure pressing against the liquid. In a carbonated drink, If you lower the temperature of the liquid, the lower energy of the CO2 molecules (the fizz) in the drink means more of the gas stays dissolved in the liquid instead of escaping into the air at the top of the bottle It's why any time you look up the boiling point of an element, it gives you the psi as well. It's also why if you were to go into space your body would start immediately boiling because the atmospheric pressure is 0.

[@MoxHypKa]

My body is not a liquid to boil in open space.

[@willgloryo216]

Pls can someone explain why this reduces the psi

[@belcurve]

@@willgloryo216 so gas is different than solids or liquids in that the molecules are not attached to each other. they float around in space and bump into each other. This is the reason that Gasses can be compressed or expanded but solids and liquids cannot. PSI is a direct result of how compacted of a space those molecules are in. The atmospheric pressure psi is a result of gravity on the molecules in the air pressing it down. Think about like oxygen tanks, how if you remove the cap the oxygen starts shooting out because it's pressurized in the tank. In the example with a syringe, he has a small amount of gas in the tube. Remember the psi is a result of the molecules of gas bouncing around in there. When he pulls back the plunger, suddenly the same number of gas molecules have much more room to bounce around in, which makes it a lower psi.

[@willgloryo216]

@@belcurve ohh that makes a lot of sense thx but does that mean that the forces of attraction between the molecules arent high enough to warrant the liquid staying as a gas?

Michael is the type of guy who would cool down the water by boiling it

[@ericolens3]

ugh, i hate this statement so much since boiling is generally 100 C or 212 F since the atmospheric pressure is ASSUMED. but now you alter the pressure but dont SAY youre altering the pressure. so your statment of cold boiling refrains from mentioning CHANGING the pressure. im not inherently mad at you. but when its political crap and then say A topic and C topic but omit the underlying parts the Topic B played in making Topic A and C related. i cant name any right now since there are many moving parts in a A and C topic leap of correlation not being causation. black, criminality, and poor is one of them though but its super analyzed already and sometimes overly simplified or red herringed to the point its not worth it. same with other politcal topics. but yeah cold boiling omiting the PRESSURE adjustment is the type of infomation omission that is used to ugh lie about so much by side stepping the truth then saying, i never said i was adjusting the heat. Lies of Omission is what i call it or Deception by omission. it pisses me off. "the burden of proof" is for the other party to find. witch hunts for the truth if you will.

best explanation of pressure / temperature differentials I've ever seen

[@Eduardo_Espinoza]

Do differentials mean they're equal ?

[@Repetoire]

​​@@Eduardo_Espinoza differentials means there is a difference in pressure and they are equalizing. It's like a gradient, the molecules go from where there is a lot of pressure to where there is less. They boil up from the high pressure liquid part to the low pressure part thanks to the differential in pressure. The term differential is more used in engineering than chemistry or physics in chemistry we would not say differential but rather deltaP for pressure, deltaH for temperature, Delta being a triangle.

[@Eduardo_Espinoza]

So differentials are like a steam engine? So the entropy is trying to equal out?@@Repetoire thanks for the reply :)

In high school I participated in a voluntary chemistry lab course, and part of the coursework required vacuum filtering something. We managed to pull high enough of a vacuum to start boiling the already filtered water in the receiving flask, and thus created a dilemma. Either we let the pump run and create more of a vacuum, thus getting all the fittings stuck, or turn down the pump and let the boiling water flow back through the tube and into the pump. Luckily it was a cheap water aspirator, so no harm was done.

I work in a power plant that has an absorption chiller. It works on this same principle, essentially refrigerating by boiling water. The water gets 'absorbed' by a strong lithulium bromide solution (which has a high affinity for attracting moisture) and that causes the pressure in the vessel to drop. The pressure drop causes the water to boil, even at room temperature, which then causes it to cool further so that it can be used to refrigerate.

An interesting side note that it takes far far more energy to change the phase of water than to raise its temperature. As in it takes more energy to turn 100 degree water into steam, then it would to take 75 degree water to 100 degrees for example.
