Question: What is the change in internal energy for an ideal gas undergoing an isochoric process?

Options:

Correct Answer: Equal to the heat added

Solution:

In an isochoric process, the volume remains constant, and the change in internal energy is equal to the heat added to the system.

What is the change in internal energy for an ideal gas undergoing an isochoric process?

Step 1: Understand what an isochoric process is. It is a process where the volume of the gas does not change.
Step 2: Know that internal energy is a measure of the energy contained within the gas due to its temperature and molecular motion.
Step 3: Realize that during an isochoric process, since the volume is constant, no work is done on or by the gas.
Step 4: Remember that the change in internal energy (ΔU) for an ideal gas is related to the heat (Q) added to the system.
Step 5: Conclude that in an isochoric process, the change in internal energy is equal to the heat added: ΔU = Q.
