Heated molecules causes molecules to bounce into each other separating them. As molecules separate, their density, the amount of matter found in a given volume or space, decreases. Cooled molecules are not that loose and start to get packed together if it gets frozen.

What happens to space between molecules as they cool?
Molecules take up less space as they cool. The space contains more molecules.
What happens to the molecules of a liquid when it is cool?
When ice cools it shrinks
What happens to acetone molecules when you add heat to a breaker of liquid acetone?
Acetone molecules evaporate when you add heat to a beaker of liquid acetone.
What happens to water molecules as ice melts?
the molecules absorb heat and start moving rapidly changing from solid to liquid
Does Water molecules dissociate to form h o2 ions?
Water's high heat of vaporization allows it to cool us off when we sweat
What happens to molecules from which heat is removed?
The molecules move slower when heat is removed.
What happens to space between molecules as they cool?
Molecules take up less space as they cool. The space contains more molecules.
What happens when molecules are removed from heat?
the molecules will decrease in motion
What happens to the molecules when a material is heated up or cooled down?
Molecules heat up or cool down. like when you rub your hands together you get warmer and when you go out in the cold you get cold quickly.
What happens when fast moving molecules touch other molecules?
Heat transfer
What happens to the molecules of a liquid when it is cool?
When ice cools it shrinks
What happens to the speed of molecules as they absorb heat?
molecules are moving faster and faster so more heat gets absorbed
Why do molecules move when heated?
So when molecules are heated, the heat is so intense that they have to move around for them to cool down.
What happens to wood molecules when you heat them?
they start shaking......the more you heat them, the faster they shake
What happens to acetone molecules when you add heat to a breaker of liquid acetone?
Acetone molecules evaporate when you add heat to a beaker of liquid acetone.
What happens to the molecules of a substance when it is melted?
the molecules vibrate, faster and faster as the heat increases then they become disordered
When sweat evaporates and the the water molecules absorb heat energy why is this important?
they absorb your heat off your skin to keep you cool.
