100
this phase has a definite shape and and definite volume, the particles do not move much and are close
What is solid
100

Temperature is directly proportional to 

average kinetic energy of particles 

100
liquid to a solid
What is freezing?
100

What does a phase diagram show? 

What temperatures and pressures each phases of a substance exist at 

100

The amount of space occupied by a substance.

Volume

200
this phase does not have a definite shape or volume, the particles tend to move fast and are far apart
What is gas?
200
how hot or cold something is
What is temperature?
200

Phase change in which liquid turns to gas.

Vaporization/Boiling

200

What is measured on the x (horizontal axis) of a phase diagram? 

Temperature 

200

A continuous force exerted on an object.

Pressure

300
this phase does not have a definite shape but has a definite volume, the particles are free to move
What is liquid?
300

What unit of temperature has no negative value?

Kelvin

300
change from liquid to gas at the surface level
What is vaporization or evaporation?
300

What is measured on the y (vertical) axis on a phase diagram? 

Pressure 

300

What is the relationship between volume and pressure? 

Inversely proportional (when volume goes up, pressure goes down) 

400

What phase change turns a gas directly into a solid? 

Deposition

400

Temperature in which water turns from a liquid to a gas (in Celsius)

100 Degrees 

400

When a solid turns straight into a gas 

Sublimation 

400

What is a tripe point on a phase diagram? 

The temperature and pressure in which all three phases of a substance can exist? 

400
What is the relationship between volume and temperature? 

When temperature increases, the amount of space (volume) of a gas also increases 

500
What is considered the 4th phase of matter? 

Plasma

500

Temperature in which water turns from a liquid to a solid 

0 Degrees Celsius 

500

Explain why the can imploded in on itself during the lab last week 

Heating the water in the can allows the gas to expand. Dipping in the mouth of the can in cool water leaves the gas with nowhere to go. The temperature change allows the gas to condense, have a lower volume and lower pressure. The pressure inside the can is lower than the pressure outside that can and it implodes. 

500

What is the critical point? 

The temperature and pressure in which the liquid and gas phase are indistinguishable

500

At what altitudes does atmospheric pressure decrease? How does that affect boiling point? 

High altitudes have less atmospheric pressure. Boiling point decreases
