WebMar 19, 2024 · Heat flows from a system of higher temperature to one of lower temperature as the decrease in entropy of the hotter system due to a decrease, du, in internal energy is less than the increase in entropy of the colder system due to an increase, du, in internal energy, so the entropy of the universe increases. WebIf you want to add internal energy, i.e. get these particles moving faster, we can heat it up so put this above a flame or on a hot plate, and heat will flow into the gas which will cause these particles to move faster and faster. That's one way to do it, to add heat. The other way to do it is to do work on the gas.

WebFirst rule: Cheap things first! Most furnaces or air handlers have multiple speed connections (taps). Perhaps you can raise fan speed on the unit. If you do have too much airflow on the shorter duct runs, you will need to throttle back that air. Dampers located on your grilles or registers are not very useful for this purpose and can cause a ...
