Energy Transfer By Heating

Question 1

3 ways that heat can be transferred.

Answer 1

Heat can be transferred from one place to another by conduction, convection and radiation.

Question 2

Infrared

Answer 2

Infrared radiation is a type of electromagnetic radiation, which involves waves rather than particles. This means that, unlike conduction and convection, radiation can even pass through the vacuum of space.

Question 3

Kinetic Theory

Answer 3

The kinetic particle theory explains the properties of the different states of matter. The particles in solids, liquids and gases have different amounts of energy. They are arranged differently and move in different ways.

Question 4

Properties Of Solids

Answer 4

They have a fixed shape and cannot flow. They are like this because the particles cannot move from place to place.

Question 5

Properties Of Solids

Answer 5

They cannot be compressed or squashed. This is because the particles are close together and have no space to move into.

Question 6

Properties Of Liquids

Answer 6

They flow and take the shape of their container. This is because the particles can move around each other.

Question 7

Properties Of Liquids

Answer 7

They cannot be compressed or squashed. This is because the particles are close together and have no space to move into.

Question 8

Properties Of Gases

Answer 8

They flow and completely fill their container. This is because the particles can move quickly in all directions.

Question 9

Properties Of Gases

Answer 9

They can be compressed of squashed. This is because the particles are far apart and have space to move into

Question 10

Conduction

Answer 10

Metals are good conductors of heat but non-metals and gases are usually poor conductors of heat. Poor conductors of heat are called insulators.

Question 11

Heat Energy

Answer 11

Heat energy can move through a substance by conduction. Heat energy is conducted from the hot end of an object to the cold end.
