Question

Describe the motion of molecules in an ice cube and in a radiator in winter

Answer 1

The motion of molecules in a ice cube are so packed together that they can't move freely like molecules in liquids and gases

Answer 2

Molecules in an ice cube have lower kinetic energy than molecules in a radiator.

Molecules in an ice cube move more slowly than molecules in a radiator. They collide with less force than molecules in a radiator.

When in direct contact, the fast-moving molecules in the radiator collide with the slow-moving molecules in the ice cube.

Kinetic energy is transferred from the molecules in the radiator to the molecules in the ice cube, causing a slowdown of the radiator molecules and an acceleration of the ice molecules.
