The temperature of an ideal gas increases in an:
Correct answer: B. Adiabatic compression
- A. Isothermal process
- B. Adiabatic compression
- C. Isobaric expansion
- D. Isochoric cooling
Explanation
In adiabatic compression, work done on gas with no heat exchange (Q=0), increasing its internal energy and its temperature. Other processes maintain or low temperature.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
