A sample of argon gas is contained in a container kept at constant volume. The temperature of the gas is slowly increased by step-wise increments. The energy absorbed by the sample at each increment is recorded, and the average energy of the gas at each temperature is calculated. Using this data, the student is asked to determine the heat capacity of the gas at constant volume and explain why this value only depends on the temperature of the system.
