Anything that has mass and takes up space is called...
What is matter?
This state of matter keeps its own shape and volume.
What is a solid?
This process happens when ice changes into liquid water.
What is melting?
This is the amount of matter in an object.
What is mass?
This theory explains that all matter is made of tiny particles.
What is particle theory?
This state of matter takes the shape of its container but keeps the same volume.
What is a liquid?
This process happens when liquid water turns into ice.
What is freezing?
This is the amount of space something takes up.
Which one is made up of matter: light, sound, or water?
What is water?
This state of matter spreads out to fill its container.
What is a gas?
This process happens when liquid water changes into water vapour.
What is evaporation?
This property compares mass with volume.
What is density?
DAILY DOUBLE: An upside-down cup is pushed straight down into water. The water does not completely fill the cup. Explain why.
What is... The cup has air trapped inside it. The air is matter and takes up space, so the water cannot fill that space.
These two states of matter take the shape of their container.
What are liquids and gases?
This happens when water vapour changes into liquid water.
What is condensation?
When air is pushed into a smaller space, this process is called what?
What is compression?
A sealed container looks empty. Explain why it is not actually empty.
What is the container holds air, and air is matter?
A mystery substance has a fixed volume, but it does not have a fixed shape. What state of matter is it?
What is a liquid?
An ice cube is heated until it becomes water vapour. Name the two changes that happen in order.
What is melting and evaporation?
Two balls have the same mass, but Ball A is smaller than Ball B. Which ball is denser?
What is Ball A?
