Questions & Step-by-Step Solutions
In an isochoric process, what happens to the internal energy of a gas when heat is added?
Step 1: Understand what an isochoric process is. It means the volume of the gas does not change.
Step 2: Know that internal energy is the energy contained within the gas due to its temperature and molecular motion.
Step 3: Recognize that when heat is added to the gas in an isochoric process, the gas cannot expand because the volume is constant.
Step 4: Since the gas cannot do work on its surroundings (because the volume is constant), all the heat added goes into increasing the internal energy of the gas.
Step 5: Conclude that in an isochoric process, adding heat increases the internal energy of the gas.
