Changes in State by Definition
Solid into Gas
Sublimation
Particles vibrate in place
Solid
You pick up a cold glass and find a ring of water on the table under it. What happened?
Condensation
Put the states of matter in order from least to most energy.
Solid, Liquid, Gas
Solid into Liquid
Melting
Particles are able to slide past each other.
Liquid
You start with 2 cups of water. After boiling it for a while, you let it cool. Now there is only 1.5 cups of water. Why is some of the water gone?
It turned into a gas.
If a liquid loses heat to the environment, what will happen to the liquid's temperature?
It will have a lower temperature.
Gas into Liquid
Condensation
Particles have more energy than solids, so they can take the shape of their container
Liquid
What happens when a puddle of water absorbs energy from the sun?
It evaporates.
Why do ice cubes melt?
They absorb heat.
A liquid changes to a solid, no specific temperature required.
Solidification
Particles have the most energy, so they can fill their container.
Gas
A substance has particles vibrating in place, a while later, the particles are farther apart and able to slide past each other. What changed to what?
solid to gas
What's the boiling point of water in either Celsius or Fahrenheit?
100 degrees Celsius
212 degrees Fahrenheit
Liquid to gas with boiling water.
Vaporization
This has the least amount of energy.
Solid
When ice begins to melt, what do the particles start to do?
Move more freely, or spread apart, or slide past each other
