Asample of gas has increased in temperature from 20° celsius to 22° celsius. which of the following happens as the temperature of the gas goes up?

the gas undergoes a phase change.
the velocity of the gas particles decreases.
the kinetic energy of the particles increases.
an exothermic reaction is more likely to occur.

The kinetic energy of the particles increases.

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if temperature is increased, average kinetic energy of the system also increases.

Also the velocity of the particles also increase as .

d.) circle motion requires a force to give it a centripetal acceleration.
