Challenge: Problem 2

1 the systemic relationship PV = RT 2 a decrease of temperature 3 internal energy a function of temperature only 4 the inversion temperature of a gas: in going from a high pressure region to a low pressure region a gas can cool if it starts below the inversion temperature 5 reduction of pressure 6 the condition of a liquid 7 increase of volume 8 the specific heat does not vary with temperature 9 absolute temperature T 10 the number of molecules in one gram molecule of any gas is a constant (Avogadro's number) 11 ionization of the gas 12 adiabatic change of state 13 the walls of the enclosure of the gas consist of molecules 14 attractive forces between molecules 15 shape of molecules 16 finite size of molecules 17 internal structure of molecules 18 average kinetic energy of molecules 19 repulsive forces between molecules 20 the magnitude of the internal energy when T = O
