(A): During an adiabatic compression temperature of an ideal gas increases.
(R): Internal energy of a gas can be changed even without addition or withdrawn of heat but by doing work.
(R): Internal energy of a gas can be changed even without addition or withdrawn of heat but by doing work.
View answer and explanation
Correct option: A
Both (A) and (R) are true and (R) is the correct explanation of (A)
Option A is correct because during adiabatic compression, work is done on the gas, increasing its internal energy and thus its temperature. The reason correctly explains this.
