Question

2.30 moles of argon gas at 252 K are kept in a container. (a) If the temperature of the gas is increased to 455 K at constant volume, how much heat was transferred to the gas? The molar specific heat capacity of argon at constant volume is 12.5 J/mol. (b) What is the change in internal energy of the gas due to this change in temperature at constant volume? (c) Suppose the temperature of the gas is increased from 252 K to 455 K at constant pressure, how much heat is transferred to the gas? The molar specific heat capacity of argon at constant pressure is 20.8 J/mol. (d) How much work is done on the gas as its temperature increases at constant pressure?
