What are the 3 phases of matter?
Solid, Liquid, Gas
100
A liquid turning into a solid
What is freezing?
100
Type of energy in motion
What is kinetic energy?
100
Water freezes at this temperature
What is 0° C 32° F
200
The particles in this phase are very spread out and often collide with each other
What is a gas?
200
A solid turning into a liquid
What is melting?
200
Type of energy that could be set into motion.
What is the potential energy?
200
Water boils at this temperature
What is 100°C or 212° F
300
The particles in this phase are packed tightly together and have little motion
What is a solid?
300
A gas turning into a liquid (water drops on the inside of a window)
What is condensation?
300
Heat energy does this in order to cause a phase change
What is break the attraction between particles?
300
Salt does this to the boiling point of water
What is lowers it?
400
The particles in this phase are somewhat spread out and flow back and forth
What is a liquid?
400
A liquid turning into a gas over a long period of time
What is evaporation?
400
As the energy of a substance increases, so does this
What is the temperature?
400
The lowest possible temperature where nothing could be colder and no heat energy remains in a substance.
What is absolute zero?
500
Give an example of each of the phases of matter
solid (ice), liquid (water), gas (steam)
500
A liquid turning into a gas in a short amount of time
What is vaporization?
500
What happens to the temperature during a phase change
It stays constant or the SAME
500
Can Scientists cool matter to absolute zero?
No because you can't totally take away all sources of heat.
