States of Matter
This state of matter has particles that vibrate in place in a fixed arrangement.
Solid
A change from one state of matter to another.
Phase change
The temperature that a solid will turn into a liquid
Melting Point
type of energy an object has when it is in motion
Kinetic Energy
What happens to the pressure of a gas when its temperature increases (at a constant volume)?
The pressure increases
Which state of matter has particles that are close together, but move freely past one another?
Liquid
A change in state from a solid to a liquid.
Melting
The force of the outward push of a gas over an area of the walls of the container.
Pressure
A liquid begins to slow down and the particles move closer together. This is because...

Bromine has a melting point of -7.2 and a Boiling Point of 58 degrees. If the temperature is 22 degrees what state of matter will it be in?
Liquid
This state of matter has indefinite shape and indefinite volume, and the particles move freely and rapidly.
Gas
A change in state from a liquid to a gas.
Vaporization/Evaporation
A measure of the average kinetic energy of an object's particles.

False - Water takes up more space as a solid.
A change in state from a liquid to a solid.
Freezing
The temperature at which a liquid turns into a gas.
Boiling point

Vibrations
A change in state from a gas to a liquid.
Condensation
The total kinetic and potential energy of particles
Thermal Energy
The process by which a substance changes directly from a solid to a gas, skipping the liquid phase.
Sublimation
