List the three phase changes that can be identified as endothermic.
Sublimation, Melting, Vaporization
List the three phase changes that can be identifed as being exothermic.
Deposition, Condensation, Freezing
When more heat is added, the particles in a solid move around more. When there is enough heat, the solid will ___ into a liquid
melt
When the temperature decreases, water vapor (gas) slows down and will turn back into liquid water. What is this phase change?
Condensation
The Sun helps to _________ water and turn into from a liquid to a gas.
evaporate
In order for a liquid to turn into a gas you need endothermic or exothermic change?
endothermic
When the temperature gets really low, gas particles can skip the liquid phase and instantly turn into solid. Snow forms this way in the cloud. This is the phase change called ________.
Deposition
When the air gets cooler, water droplets on grass can turn into frost. This is an example of
Freezing
In ______, the atoms have SO MUCH ENERGY, that they all travel super fast and are impossible to see.
Gas
In __________, the atoms have more energy and move around more than they would in a solid object, but less energy than in a gas.
Liquids
In every _____, the atoms are packed tightly together and vibrate in place.
Solid
Sometimes, a solid can turn into a gas by skipping the liquid phase. Dry Ice is an example of this process, known as __________.
Sublimation
Sublimation is a _______ into a _________.
Solid -> Gas
Vaporization is ______ into _______.
Liquid ---> Gas
Melting is a ________ into __________.
Solid ----> Liquid
Freezing is ______ into _______.
Liquid ---> Solid
