States of Matter

Particles (molecules) in a ______________________ have more energy than the other states of matter.

• gas
• solid
• liquid

At higher temperatures

• particles in an object have less energy
• particles in an object move faster
• a gas contracts

A gas

• has a definite shape but no definite volume
• has a definite volume but no definite shape
• has fast-moving particles

Define a liquid.

• Indefinite shape, indefinite volume
• Definite shape, definite volume
• Found in stars
• Definite volume, indefinite shape

The state of matter that has no definite size or shape is

• Solid
• Liquid
• Gas

Particles of a liquid

• are tightly packed together and stay in a fixed position.
• have no viscosity.
• decrease in volume with increasing temperature.
• are free to move around one another but still touch.

Absolute zero temperature is characterized by:

• particles moving at their fastest possible rate
• particles in matter moving in a state that creates a liquid
• particles are moving in a state that maintains a gas
• particles in matter are not moving at all

In terms of the properties of matter, when you add energy which is going to happen:

• solid to liquid
• gas to liquid
• liquid to solid
• gas to solid

In terms of changing from one state of matter to another, when you take away energy, which will happen?

• liquid to gas
• solid to liquid
• gas to liquid
• solid to gas

If the pressure and the amount of gas are constant.
As the temperature of an enclosed gas increases, the volume 

• increases 
• does not change
• decreases
