What happens to the internal energy of an ideal gas during an adiabatic compression?.
- A.It remains constant.
- B.It increases.
- C.It decreases.
- D.It fluctuates.
Model answer
What a good answer should say
- It increases.
Explanation
Why this works
In an adiabatic compression, work is done on the gas, which increases its internal energy, leading to a rise in temperature without any heat exchange.
