Anything that is a liquid.
100
Name an example of a gas.
Anything that is a gas.
100
Name a physical property of matter.
Physical properties of matter include: size, shape, color, texture and density.
100
What causes matter to change from one state to another?
Matter changes states when heat is either added to it or taken away from it.
200
Describe the movement of molecules in a solid.
They vibrate in place.
200
Describe the movement of molecules of a liquid.
They move faster and spread further from each other then a solid.
200
Describe the speed of molecules in a gas.
The molecules in a gas move very quickly and are spread very far apart.
200
Name an example of a chemical property.
Chemical properties of matter include: rusting or burning.
200
What is it called when a solid changes to a liquid?
It is called melting.
300
Describe the pattern of the molecules in a solid.
They are tightly packed together with hardly any space.
300
Describe the shape of a liquid.
A liquid does not have its own shape and it will take the shape of the container that it is in.
300
What is the color of most gases?
Most gases are translucent or see-through (clear).
300
Describe what texture means.
The texture of an object is how it looks and feels.
300
What is it called when a liquid changes to a solid?
It is called freezing.
400
Describe the shape of a solid.
A solid will always keep its own shape.
400

Describe what happens when heat is added to a liquid.

A liquid will evaporate and become a gas when it is heated.

400
Describe the shape of a gas.
Gases spread out throughout the shape of the room or environment that they are in.
400
Describe what density means.
Density is how much an object weighs, based on how closely-packed its molecules are.
400
What is it called when a liquid changes to a gas?
It is called evaporation.
500
Describe what happens when heat is added to a solid.
When heat is added to a solid, it melts and turns into a liquid.
500
Describe what happens when heat is taken away from a liquid.
The liquid will turn into a solid.
500
Describe what happens when heat is taken away from a gas.
When heat is taken away from a gas, it goes through condensation and becomes a liquid.
500
What are things that could cause something to have a chemical change?
A chemical change can be created by heat (burning), oxygen (rusting), or light (yellowing).
500
What is it called when a gas changes into a liquid?
It is called condensation.
