Try this first
Describe the energy transfer that occurs during an adiabatic process involving an ideal gas.
Model answer
What a good answer should say
- In an adiabatic process, no heat is exchanged with the surroundings.
- The work done on or by the gas results in a change in its internal energy, which causes a change in temperature.
- The first law of thermodynamics states that the change in internal energy is equal to the work done on the gas.
Explanation
Why this works
This answer effectively explains the concept of an adiabatic process by emphasizing the lack of heat exchange and the relationship between work and internal energy. It tests the ability to apply the first law of thermodynamics in a different context.
