Question

Which of the following explains why hot liquids have a greater average energy of motion than cold liquids? *

Hot liquids have more electrons
Cold liquids have more electrons.
Particles in hot liquids move faster than particles in cold liquids
Particles in cold liquids move faster than particles in hot liquids.

Answer 1

Particles in hot liquids move faster than particles in cold liquids. The faster a particle moves, the greater its kinetic energy.

The number of electrons in a particle has nothing to do with its kinetic energy.

Particles in cold liquids move more slowly than particles in hot liquids.
