Q: The heat capacity at constant volume (Cv) for an ideal gas is related to which of the following? (2023)
Solution: The heat capacity at constant volume (Cv) is directly related to the change in internal energy of the system.
Steps: 4
Step 1: Understand what heat capacity at constant volume (Cv) means. It is the amount of heat needed to raise the temperature of a gas when the volume is kept constant.
Step 2: Recognize that when a gas is heated at constant volume, the energy added goes into increasing the internal energy of the gas.
Step 3: Realize that internal energy is the total energy contained within the gas, which includes kinetic and potential energy of the gas molecules.
Step 4: Conclude that since Cv measures how much heat is needed to change the temperature of the gas at constant volume, it is directly related to the change in internal energy of the system.
