Questions & Step-by-Step Solutions
A gas expands isothermally at 300 K and absorbs 600 J of heat. What is the work done by the gas? (2023)
Step 1: Understand that an isothermal process means the temperature remains constant.
Step 2: Recall that in an isothermal expansion, the work done by the gas is equal to the heat absorbed by the gas.
Step 3: Note that the problem states the gas absorbs 600 J of heat.
Step 4: Since the work done by the gas is equal to the heat absorbed, we conclude that the work done is also 600 J.
Isothermal Process – In an isothermal process, the temperature remains constant, and the internal energy change is zero, meaning the heat absorbed by the gas is equal to the work done by the gas.
