What is conduction?
Transfer of heat between two bodies that are in contact with each other.
What is convection?
It occurs when heat is transferred by the movement of liquids or gases.
What is radiation?
The flow of heat between objects that are not in contact with each other.
How are the particles arranged in a liquid?
They are loosely arranged which means they do not have a fixed shape like solids, but they rather take the shape of the container they are in.
How are the particles arranged in a solid?
The particles are packed tightly together in a regular pattern.
How are the particles arranged in a gas?
They are well separated with no regular arrangement.
What is heat?
Heat is a form of Energy moving from a hotter body to a colder one.
What is temperature?
Temperature is the measurement of the average kinetic Energy of the particles of a body.
Use the particle theory to explain why the shape of a piece of metal in its solid state doesn't change when you press it hard?
Because its particles are packed so tightly together that it is impossible to bend metal without a special machine.
Name the change in state when a gas turns into a liquid
Condensation
Which two states of matter have the ability to flow?
Liquid and gas
What happens to the movement of particles when a substance is heated.
The particles start moving faster and, because of this, its temperature rises.
Name the change in state when a solid turns into gas without passing by the liquid phase.
Sublimation
What are the three states of matter?
Solid, liquid and gas.
Which state of matter can be easily compressed?
Gas
Identify 2 properties of a liquid and provide reasons for these properties.
It can flow and it takes the shape of its container. This is because the particles move freely sliding past each other.
