200
In a solid, particles do not move around each other, but they do
Vibrate in place
200
What state of matter has a definite shape and a definite volume?
What is Solid?

The two types of vaporization include...
What are evaporation and boiling?
200
When a liquid is freezing into a solid, thermal energy is...
(added/ taken away)
What is taken away?
300
What state of matter is milk?
Liquid
300
Helium is an example of which state of matter?
What is a gas?
300
The total kinetic and potential energy of all the particles in an object or substance.
What is thermal energy?
300
The change in state from a gas to a liquid.
What is condensation?
300
What do you notice about the boiling point and condensing point on this graph?
Answers my vary:
*Boiling and condensing points are the same, because they are the temperatures at which change occurs.
*Temperatures remain the same as substances change state.

500
What is the change in state when a solid changes directly to a gas?
What is sublimation?
500
Which has more thermal energy, a whale or a mouse? Why?
What is a whale? A whale has more thermal energy because it is larger. A mouse might have a similar temperature, but it is smaller.
