Question

If a gas expands at constant temperature, it indicates that (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

Tardigrade Admin · Accepted Answer

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

Q. If a gas expands at constant temperature, it indicates that

kinetic energy of molecules decreases

pressure of the gas increases

kinetic energy of molecules remains same

number of the molecules of gas increases

$K E = \frac{3}{2} RT$ or $K E \propto T$
Here, the temperature of gas remains constant, hence kinetic energy of molecules remains the same.

KE=23​RT or KE∝T Here, the temperature of gas remains constant, hence kinetic energy of molecules remains the same.

$K E = \frac{3}{2} RT$ or $K E \propto T$
Here, the temperature of gas remains constant, hence kinetic energy of molecules remains the same.
