Did your answers include these concepts?
D 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
