Which is true about the temperature of a gas?

at a higher temperature, the particles have a higher average kinetic energy.
at a higher temperature, the volume of the gas is smaller.
at a lower temperature, there are more particles in the gas.
at a lower temperature, the particles in the gas move faster.

These traits describe either a chemical or a nuclear reaction. which statements describe a nuclear reaction? check all that apply. involves the loss, gain, or sharing of electrons may involve a change in total mass involve relatively low energy changes occur outside the nucleus involve very high-energy changes involve changes in nuclides when decay occurs
