What happens to the average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume? explain your answer.

Gas molecules move constantly, any object in constant motion possesses kinetic energy. Overall at constant temperature and volume, the molecules of a gas have average kinetic energy.

Individual molecules yet have variation in kinetic energies because of distribution in speeds. When collisions among gas molecules occur, it gives rise to the distribution of speeds.

Because the collisions among gas particles are elastic and hence there is no loss of energy, and average kinetic energy of gas molecules does not change and remains the same.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
