States of Matter

In which state of matter are particles packed tightly together in fixed positions?

• gas 
• solid
• liquid
• plasma

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 in a container but are in close contact with one another

In which state of matter do particles spread apart and fill all the space available to them? 

• crystal
• liquid
• gas
• solid

The change from a  liquid to solid, or the reverse of melting, is called

• condensation
• boiling
• sublimation
• freezing

During the process of sublimation

• a solid turns directly into a gas
• a solid turns into a liquid
• a gas turns directly into a solid 
•  a liquid turns into a gas

The three main states of matter are:

• Solid and liquid

• Solid, liquid and gas

• Plasma, liquid and solid

• True

• False
