When a solid is heated, the motion of the particles ________
Particles sliding past each other as the substance begins to state from a solid to a liquid is...
Changing directly from a solid to a gas is....
Molecules in a liquid go directly into the air as a gas is...
The temperature at which a substance begins to melt is...
Changing from a gas to a liquid is
Changing from a liquid to a solid is
When water freezes, the molecules move
Changing from a gas to a solid is
This forms when liquid water evaporates to become water vapor and moves up into the sky in upward-moving air.
This forms when a small drop of water freezes, falls and then gets pushed back up into a cloud. eventually it becomes a heavy ice crystal and falls to the ground
This is produced when moist air close to the ground cools enough to condense and forms liquid water.
