Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change q=m?Cs??T where Cs is specific heat and m is mass. Heat can also be transferred at a constant temperature when there is a change in state. For a process that involves a phase change q=n??H where, n is the number of moles and ?H is the enthalpy of fusion, vaporization, or sublimation. The following table provides the specific heat and enthalpy...

A Joule expansion refers to the expansion of a gas from volume V1 to volume V2 against no applied pressure, and is sometimes also called a free expansion. There is no work done, because the P of -PdV is zero. By insulating the system, this process can be done adiabatically, so there is no change in heat. For an ideal gas, the adiabatic process is also isothermal, so there is no change in thermodynamic energy, ∆U = 0 (which is...
