First Law of Thermodynamics, Basic Introduction - Internal Energy, Heat and Work - Chemistry

This chemistry video tutorial provides a basic introduction into the first law of thermodynamics. It shows the relationship between internal energy, heat, and work. It discusses the difference between the system and surroundings and distinguishes an open system from a closed system and an isolated system. In chemistry, work is positive whenever work is done on the system and work is negative whenever work is done by the system. During an exothermic process, heat flows out of the system and it flows into the system during an endothermic process.

You said exactly what I have wanted to say always to my friends when they asked of explanation why the equations are different. In chemistry we look at the material so the interal energy of the material. Some reactions occur and the energy appears as heat and work while in physics we apply heat on the material so the body gets charged up(I meant Internal energy gain here) or does some work in order to utilise the heat given.

That isn't actually true. Trading actually "can" and often "does" create new wealth. What I mean is, when trading something you can readily obtain, for something you do not have, nor have the capability of obtaining on your own, both parties generate wealth. For example, if a basket weaver trades with a spear maker, both parties leave with more than what they came in. Don't attempt to quantify by the amount of physical material exchanged, instead, consider the capability of BOTH parties prior to the exchange. The basket weaver can now hunt more efficiently, the spear maker can now gather more efficiently. I know this isn't all that important, but I thought it was something worth mentioning. :)

Y'all this man is the real deal. He prolly went to Harvard or something. I watched his vids 3 days before physics exam and got an 80%. If I watched his videos 2 weeks before, I would've just gotten a 100% without trying, engineering major, that's not childsplay. He even teaches things like derivations, proofs without even noticing, and the teachers don't teach that cause that's where they try to catch you out. Nah I hope this guy is rich or something cause what he's doing is absolutely unreal.

A college professor seeking to liven up his course had the following extra credit question an an exam. "Is Hell exothermic or endothermic? Provide sound evidence to support your answer." One of his students submitted the following answer. He started by providing all the reasons that would support both an exothermic Hell and an endothermic Hell. After several paragraphs of this he got to the main evidence and its implication. Here is his analysis. When I asked the pretty coed in the dorm room across the hall if she would sleep with me, she said she would sleep with me "the day Hell freezes over." She has not slept with me which means Hell has not frozen over and therefore must be endothermic. He received full credit.

i have a question to raise pls notice ---- is the heat sign (positive or negative) also varies depending on what perspective we are looking at.. ?? i mean let's say the heat comes from the environment to the system----- perspective of the system: the system gain heat energy from the environment, thus the heat is positive perspective of the environment: the environment transfers heat energy (energy loss from the environment), thus the heat is negative

Hello Sir, Work output is higher than work input When I computed the work done in pool (billiard) the white mother ball break the 15ball. The work brought OUT is more than the work brought IN. Let’s try to compute. F = 30lbs (White Mother Ball); D = 3ft (From the white mother ball to the first ball to strike) SOLVE FOR WORK INPUT W = F X D; W = 30lbs x 3ft = 90Ft.lbs SOLVE FOR WORK OUTPUT First two ball extreme corner of the billiard ball 2 out of 15 ball W = F X D; W = 30lbs x 3ft = 90ft.lbs X 2ball = 180 ft. lbs The remaining ball (13pcs ball) can produce more than 90 ft.lbs The computation shows that the output work done is higher than the input work done so the theory of conservation of energy is misconception. If you don't agree please show me your computation. Appreciated for your reply Thank you. Abel Urbina
