1. Under constant-volume conditions, 4200 J of heat is added to
1.4 moles of an ideal gas. As a result, the temperature of the gas
increases by 103 K. How much heat would be required to cause the
same temperature change under constant-pressure conditions? Do not
assume anything about whether the gas is monatomic, diatomic,
etc.
