16. The heat capacity (CP) for an element Z is CP = 24+5x10-3T (J/mole K), to what temperature would you have to heat Z at constant pressure to raise its molar enthalpy by 1J? (Start with Z in the state: P = 1atm, T = 298K) (A)286.4K (B)298.04K (C)541.32K (D)785.44K (E)>1000K

8. About ideal gas, (A)An ideal gas is an assemblage of volumeless noninteracting particles which obeys the ideal gas law, PV = RT. (B)The internal energy of an ideal gas arises solely from the translational motions of the gas particles and hence is a function only of temperature, (C)The enthalpy of an ideal gas is a function only of temperature, (D)The internal energy U is constant with respect to the gas volume, i.e. (dU/dV)T = 0, hence the pressure P can be expressed as P = (dS/dV)T, (E)The above are all correct.
