Solids
This state of matter has a definite shape and volume.
What is a solid?
This state of matter takes the shape of the container it is in.
What is a liquid?
This state of matter flows, but its shape and volume can change.
What is a gas?
This word describes the outline or form that something takes. Solids keep it, but liquids and gases change it.
What is shape?
These two phase changes occur between a solid and a liquid.
What is melting and freezing?
When a solid is heated enough, it changes into this state.
What is a liquid?
When the temperature decreases to a certain point a liquid will become this.
What is a solid?
This gas is the most important part of the air we breathe.
What is oxygen?
This is the amount of space that matter takes up.
What is volume?
This happens when a puddle disappears on a sunny day.
What is evaporation?
A solid will usually expand during this season?
What is Summer?
When the temperature increases to a certain point a liquid becomes this.
What is a gas?
This change in temperature usually causes gas particles to move faster and spread farther apart.
What is heating (or an increase in temperature)?
All matter is made up of these tiny things that are always moving.
What are particles?
This change happens when gas cools and turns into a liquid, like when water droplets form on a cold glass.
What is condensation?
The particles in a solid move this way.
What is vibrating in place?
This process happens to most liquids when they are cooled to very low temperatures.
What is freezing?
This gas makes up about 80% of the air we breathe.
What is nitrogen?
This term describes how tightly packed the particles are in a liquid (mass per unit of volume).
What is density?
This happens to particle movement during melting and evaporation.
What is speeds up (or increases movement)?
When the temperature increases to a certain point for a solid this occurs?
What is melting?
This is the process by which a liquid becomes a gas.
What is evaporation?
This is the name of the process when a gas turns directly into a liquid.
What is condensation?
This is a measure of how thick or sticky a liquid is or its resistance to flow.
What is viscosity?
This rare phase change skips the liquid stage and goes from solid straight to gas, like dry ice disappearing.
What is sublimation?
