Gas
What is the process of adding heat to liquid to turn it into a gas?
What are size, texture, shape, and color when talking about matter?
What are all substances made up of?
What has no definite shape or volume and molecules that move fast?
Gas
What do the particles look like in a liquid?
More attracted to each other which keeps them from spreading out a lot.
What is condensation? A. liquid - heat = solid B. gas - heat = liquid C. solid + heat = liquid D. liquid + heat = gas
Condensation is B. gas - heat = liquid

Name an example of each of the following: Melting Freezing Evaporation Condensation
When you take the heat away the gas will change into a liquid (condense). If you put the liquid in a cold place it will freeze back into a solid.
Size-small
Shape-cylinder
Texture-smooth
How can a solid go through ALL the states of matter?
Solids can melt into a liquid by applying heat. If you keep adding heat it will change into a gas.
When you take the heat away the gas will change into a liquid (condense). If you put the liquid in a cold place it will freeze back into a solid.
