What are the three main states of matter?
Solid, Gas, Liquid
What is density?
Mass per unit volume
What is a force?
A push or a pull on something
What is Ms. Rose's favorite color?

What is melting?
The process of a solid turning into a liquid.
In which state of matter do particles vibrate in place but do not move freely?
solid
How do you calculate density?
Density = Mass / Volume.
What force pulls objects toward the Earth?
Gravity

What is the term for a liquid turning into a gas?
Evaporation.
What happens to the particles in a liquid when it is heated?
The particles move faster and spread apart
Why do objects with a density less than water float?
Because they are less dense than water.
What is pressure?
Force applied over an area.
What is the law of conservation of mass?
The law stating that mass cannot be created or destroyed.
What do we call the change from a gas to a solid without becoming a liquid?
Deposition
What state of matter has a definite volume but no definite shape?
liquid
Which has a greater density: a rock or a sponge, and why?
The rock has a greater density because it is more compact and has less air inside.
How does a balloon pop?
When kinetic energy increases, causing pressure to build and apply force to the inside walls of the balloon.

What happens to air pressure as altitude increases?
