Calculate the heat capacity of a gas sample from the following information: The sam-
ple comes to equilibrium in a flask at 25°C and 121.3 kPa. A stopcock is opened
briefly, allowing the pressure to drop to 101.3 kPa. With the stopcock closed, the flask
warms, returning to 25°C, and the pressure is measured as 104.0 kPa. Determine Cp
in J mol- K- assuming the gas to be ideal and the expansion of the gas remaining
in the flask to be reversible and adiabatic.
One kg of water initially at 22 ºC is to be freeze at –1ºC. Calculate the total amount of heat (in kJ) to be removed during the cooling process? Cp(ice) = 0.5(Cpw)
