Exam-style question
Try this first
Describe the difference between isothermal and adiabatic processes in terms of energy transfer.
Model answer
What a good answer should say
- In an isothermal process, the temperature remains constant, and heat is exchanged with the surroundings to maintain this temperature, resulting in energy transfer as heat.
- In contrast, an adiabatic process occurs without heat exchange with the surroundings, leading to changes in internal energy solely due to work done on or by the system.
Explanation
Why this works
This answer effectively distinguishes between isothermal and adiabatic processes by highlighting the role of heat exchange and internal energy changes. The question assesses the student's ability to apply concepts of thermodynamics to different types of processes.
