Questions & Step-by-Step Solutions

What is the work done by a gas during isothermal expansion?
  • Step 1: Understand that isothermal expansion means the gas expands at a constant temperature.
  • Step 2: Know that during this process, the internal energy of the gas does not change.
  • Step 3: Recognize that when the gas expands, it does work on its surroundings.
  • Step 4: Remember that the work done by the gas is equal to the heat it absorbs from the surroundings.
  • Step 5: Conclude that in isothermal expansion, the work done by the gas equals the heat absorbed.
