A) kinetic energy-of molecules decreases
B) pressure of the gas increases
C) kinetic energy of molecules remains the same
D) number of the molecules of gas increases
Correct Answer: C
Solution :
Key Idea: \[KE=\frac{3}{2}RT\] \[KE\propto T\] Here, the temperature of gas remains constant, hence kinetic energy of molecules remains the same.
