If a gas expands at constant temperature, it indicates that

Options

A. Kinetic energy of molecules decreases
B. Pressure of the gas increases .
C. Kinetic energy of molecules remains the same
D. Number of the molecule of gas increases.

Explanation

Kinetic energy , `KE = (3)/(2) RT`
`KE prop T`
Here , the temperature of gas remains constant , hence kinetic energy of molecules remains the same .
