Consider 14.61 moles of an ideal diatomic gas. (a) Find the
total heat capacity of the gas at (i) constant volume and (ii)
constant pressure assuming that the molecules translate and vibrate
but do not rotate. Be sure to clearly explain how the equipartition
of energy is used to solve this problem. (b) Repeat problem (a)
above except assume that the molecules translate, rotate and
vibrate.

The constant-pressure heat capacity of a sample of a perfect gas
was found to vary with temperature according to the expression Cp
(J K−1) = 20.17 + 0.4001(T/K). Calculate q, w, ΔU, and
ΔH when the temperature is raised from 0°C to 100°C (a) at constant
pressure, (b) at constant volume.

Neon gas (a monatomic gas) and hydrogen gas (a diatomic gas) are
both held at constant volume in separate containers. Each container
contains the same number of moles n of each gas. You find
that it takes an input of 300 J of heat to increase the temperature
of the hydrogen by 2.50°C.

How many modes does a single hydrogen gas molecule have? (Assume
the vibrational modes are "frozen out").

A perfect gas has a constant volume molar heat capacity of CV ,m

heater for 65 seconds, calculate
a) q, w, T, and U for heating at a constant volume,
b) q, w, T, and H for heating at a constant pressure.

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.
2. A system gains 3080 J of heat at a constant pressure of 1.36
× 105 Pa, and its internal energy increases by 4160...
