d)atmospheric pressure

Answer 1

♥___HEY MATE HERE US YOUR ANSWER ___♥
Kinetic energy of molecules is directly proportional to temperature

Answer 2

Answer:

The correct answer is option (a).

Explanation:

Kinetic energy of the molecules is defined as an average energy possessed by the molecule due to their motion.It is given as:

$K=\frac{3RT}{2N_A}$

where,

K = Average kinetic energy

R = Gas constant

T = Temperature of the system

$N_A$ = Avogadro's number

It depends directly on the temperature of the substance.

The correct answer is option (a).
