Total kinetic energy of all the atoms that make up a sample of matter, would that be heat or

Mechanical energy

Explanation:

Mechanical energy is a result of kinetic energy plus potential energy of an atom due to the motion of electrons. As the electrons move away from the nucleus, that is to the outer orbitals the potential energy increases, and as the electrons move inward towards the nucleus the kinetic energy increases.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
