The Functional Form of the Internal Energy
... potential energy. This energy comes at the expense of kinetic energy, therefore the molecules slow and the temperature decreases. Since both the temperature and pressure are decreasing as the gas expands, JT is positive. On the other hand, if repulsive forces dominate, as the gas expands potential ...

... of ice at -40°C, and we want to heat it to a temperature of 110°C. How much heat (energy) does that take? We know that when we heat the water from 0°C to 100°C, we can calculate how much heat is necessary to add in order to accomplish this by using Q = mcΔT. However, if we plot the heat added to the ...
