What determines the average kinetic energy of particles in a gas ?

Temperature of the substance determines the average kinetic energy of particles in a gas.

Explanation:

Average kinetic energy is defined as the average of all the kinetic energies of the particles in a system. It is a measure of temperature of the particles in a gas.

The equation used to calculate the average kinetic energy of the particles is given as:

where,

R = Gas constant

T = Temperature of the gas

= Avogadro's number

E = Average kinetic energy of the particles

As, temperature is directly related to the average kinetic energy of the gas. Thus, the temperature of the particles increases, the average kinetic energy of the particles also increases and vice-versa.

Thus, temperature of the substance determines the average kinetic energy of particles in a gas.

answer; i do believe the correct answer is (river); /// good luck

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
