Which term is defined as a measure of the average kinetic energy of the particles in a sample?
(1) temperature (3) thermal energy
(2) pressure (4) chemical energy

The correct answer is Option (1).

Explanation:

Average kinetic energy is defined as the average of the kinetic energies that is associated to the particles of the sample which are in random motion.

Temperature is the measure of the average kinetic energy of the particles. Formula used for calculating the average kinetic energy is given by:

where,

K = kinetic energy

R = Gas constant

= Avogadro's constant

T = temperature

Kinetic energy is directly proportional to the temperature of the particle.

As the temperature increases, the kinetic energy of the particles also increases and vice-versa.

Hence, the correct answer is option 1.
