100
Describes how much mass is in a given volume of a material.
What is density?
100
This is a flat portion of a graph showing the temperature at which melting or freezing occurs.
What is melting point?
200
The phase of matter that maintains it volume but not its shape is this.
What is liquid?
200
The temperature scale at which water freezes at 32 and boils at 212.

The amount of space an object takes up.
What is volume?
200
This is a flat portion of the graph that shows the temperature at which boiling or condensation occurs.
What is boiling point?
300
The phase of matter that has a definite shape and a definite volume.
What is solid.

The temperature scale at which water freezes at 0 and boils at 100.
What is Celsius?
300
The transfer of heat by the motion of matter.
What is convection?

You measure the volume of liquids with this tool.
What is a graduated cylinder?
300
The amount of energy (heat) needed to increase the temperature of 1 gram of water by 1 degree C.
What is calorie?
400
This is required for matter to change from one state to another.
What is thermal energy?

400
The metric unit for measuring heat.
What is joule?
500
These are the forces between atoms or molecules that determine the phase of matter.
What is intermolecular forces?
500
The lowest possible temperature at which thermal energy is as close to zero as possible.
What is absolute zero?
500
Under this condition, matter is at the same temperature and no heat flows.
