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

Options:

Correct Answer: ΔU = Q

Solution:

In an isochoric process, the change in internal energy is equal to the heat added to the system, ΔU = Q.

What is the change in internal energy (ΔU) for an ideal gas in an isochoric process?

What is the change in internal energy (ΔU) for an ideal gas in an isochoric process?

Step 1: Understand what an isochoric process is. An isochoric process is one where the volume of the gas does not change.
Step 2: Recall that internal energy (ΔU) of an ideal gas depends on its temperature.
Step 3: In an isochoric process, since the volume is constant, any heat added to the gas will change its internal energy.
Step 4: Remember the relationship for internal energy in an isochoric process: ΔU = Q, where Q is the heat added to the system.
Step 5: Conclude that in an isochoric process, the change in internal energy is equal to the heat added.
