Question

why does all matter contain thermal energy? because particles can never stop moving because particles stop moving because all matter is cold because all matter is hot

Explanation:

Thermal energy is related to the motion of particles. According to the kinetic theory of matter, particles in matter are always in motion. Even at very low temperatures, particles have some residual motion. If particles stopped moving (which would be at absolute zero, a theoretical limit that's never actually reached in practice for all matter), there would be no thermal energy. But since particles can never truly stop moving (as reaching absolute zero for all matter is impossible), all matter has thermal energy. The options "Because particles stop moving" is incorrect as that would mean no thermal energy. "Because all matter is cold" is wrong because cold matter still has particle motion (just less energetic). "Because all matter is hot" is incorrect as not all matter is at a high - temperature "hot" state, but even "cold" matter has thermal energy.

Answer:

Because particles can never stop moving
