| | SPECIFIC HEAT CAPACITY |
 | | The kinetic energy is derived for gases, and it turns out to be (3/2)nRT for a monatomic gas, where n is the number of moles (n= m/M, mass divided by "molecular mass"), R is the universal gas law constant, and T is the absolute temperature. |
 | | If you add heat to a monatomic gas (under conditions of constant volume, otherwise some of the energy will go elsewhere due to the work of expansion), use 3/2 instead of 3 in the equation (and for a diatomic gas, use 5/2). |
 | | Set these quantities equal to each other and calculate the unknown, whatever it is. If a change of phase is involved, when hell freezes over, for example, you need to know about heat of fusion or vaporization. |
