Energy must be transferred into or out of a system in order to cause phase change.In addition changes in the energy can be directly related to pressure volume changes.If equal moles of each gas is compressed which one would have the largest pressure volume change during condensation? Heat of vaporization also given as

NaF(29.3kj/mol)
HCl(1.99KJ/mol
O2(0.45KJ/mol
CHCL3(9.20KJ/mol
