A
kinetic energy of molecules decreases
B
pressure of the gas increases
C
kinetic energy of molecules remains same
D
number of the molecules of gas increases
Solution:
$ KE=\frac{3}{2}RT $ or $ KE\propto T $
Here, the temperature of gas remains constant, hence kinetic energy of molecules remains the same.
