+Mr Kagouris: In order for our bodies to function, at the cellular level, we break apart certain molecules such as glucose and combine it with oxygen and this produces CO2, H2O and some heat. Some of the energy is used to make other molecules, some of it is used to contract muscles. (Don’t take my word for it since I’m not an expert in biochemistry).

I've seen a lot of channels attempt to talk about things they don't really understand and end up looking stupid when they butcher it, all because they want to look smarter than they actually are. It's good that they are trying to learn new things and expand their knowledge, but people need to learn to acknowledge their limits better.

I would like to add to Gregg's explanation. All of the heat inside a CPU is a result of something called Joule heating. Heat is simply kinetic energy (indeed all forms of energy are either kinetic or potential). Since electrons have rest mass and since they are what is traveling through the circuits, they bump into the atoms of the wire creating a sort of kinetic turbulence. This is what heat is at the most fundamental level. Whether it be in an electrical circuit, your car engine, or when you rub your hands together, heat is generated from this principle. In other words, heat IS motion whether it be at the sub-atomic level up to the size of galaxies. Now I think an explanation of temperature and heat is in order because this is something lots of non-scientists or engineers have a hard time understanding. Heat is not temperature, they are related, but not the same. A good example of what I mean is the following question: Which is hotter -- an iceberg in the north Atlantic or your CPU running Prime95? If you answered your CPU, you are WRONG. The iceberg is hotter but it has a lower temperature. Why? Because heat is essentially energy and energy is related to mass (Remember Einstein's E=MC^2). Since the iceberg is so much larger, it has more total energy (more molecules moving around creating heat). However, it is much lower in temperature. It turns out that temperature is the AVERAGE heat in a system, not an absolute measurement of total energy. So if you put a thermometer probe anywhere on the iceberg it will be somewhere around freezing or below, but it does contain far more heat in total than a CPU at 70°C. I mention this because I see this confusion arise A LOT on computer enthusiast forums when it comes to radiators and cooling. Most people don't get it. Now, all regular matter (except superconductive materials) has electrical resistance. It just so happens that highly conductive materials like metals have a low resistivity while insulators like rubber or glass have a very high resistivity (this is what defines them as conductors or insulators or semi-conductors). The problem we have with heat in electrical circuits is a result of the fact that the stuff the circuits are made of has this inherent resistance. This fact is probably known by most people reading this, so this is nothing that insightful. However, there is another effect I would like to mention that's related but probably not as well known by average enthusiasts. When metals experience a rise in temperature (even if there's no electrical current), the resistance also rises, which means the metal is less conductive than it was. This is called the temperature coefficient of resistance and electrical engineers are very familiar with the principle. (In fact, this is how some thermometers work -- they read the resistance of a metal (or ceramic) element and calculate the temperature based on this resistance change. Indeed the thermometers on our CPU die themselves work this way). What this means is that since the resistance has risen due to heat, you need more current to overcome that resistance. More current means more kinetic energy (heat) flowing through the wire and yet even a higher temperature. And the higher temperature means yet another rise in electrical resistance. You see where this is going. It's a vicious cycle. If you are doing extreme cooling like liquid nitrogen, you can counter-act this resistance rise (with such cooling you are actually making the metals more conductive in the circuit), but ultimately your clock speeds will be limited to inherent circuit design and limitations irrespective of heat. There is a solution to this problem, though. It's called super-conductivity. The problem with superconductivity as we know it today is that we haven't identified any materials that can superconduct at room temperatures (or anywhere close). These materials we have now need to be in environments at WAY below 0°C. However, this doesn't mean advances wont be made and that someday we may identify a material that can superconduct at room temperature (or higher). Nobel prizes have been handed out in past decades to scientists identifying materials that increase the superconducting temperature by a few degrees (when thought impossible) so there is no law of physics that says it is impossible. This is a major problem in condensed matter physics and lots of research is going into it. If a material is identified (and it is cheap enough), it will revolutionize technology like we haven't seen since the invention of the transistor itself. It will allow for SUPER efficient microchips (that use milliwatts instead of hundreds of watts). Chips have already been made in labs that run at 6 Ghz and use a few milliwatts of power. The problem is you need elaborate sub-zero cooling to make them work at all (the cooling isn't to fight heat, but to make the material itself superconductive).

some thing about quantum tunneling it's effect that explains why subatomic particles can pass barriers they are not supposed to in this case electrons passing insulating barriers in transistors and it's cause an effect called leakage. and a bit explanation about it, the effect is statistical that means you can't determine which and when electron will pass the barrier but you can determine the odds for it, and the odds increase as you shrink things down. in matter of fact this phenomenon can be applied to our daily world but the odds are so slim it literately impossible to happen. bit further explanation to the phenomenon can be explained with the wave-particle concept.
