Matter

Question 1

How to identify matter?

Answer 1

If something has mass and takes up space.

Question 2

How to measure mass?

Answer 2

g/kg, measured with an electronic balance.

Question 3

How to measure volume?

Answer 3

cm3/L, measured with a graduated cylinder or ruler.

Question 4

Solid

Answer 4

• can be weighed
• shape cannot be changed
• takes up space
• cannot be compressed as the particles are tightly pact together (cannot slide/move over each other, only vibrate)

Question 5

Liquid

Answer 5

• can be weighed
• can change shape
• takes up space
• can be compressed as the particles are further apart and can move/slide over each other
• particles have more energy

Question 6

Gas

Answer 6

• can be weighed
• can change shape
• takes up space
• can be compressed as the particles are able to move freely/have lots of energy

Question 7

Forces in a solid?

Answer 7

They are strong and help hold the particles in a regular pattern.

Question 8

Forces in a liquid?

Answer 8

They are weaker than a solid, and as a result keep the particles close together but in a random pattern.

Question 9

Forces in a gas?

Answer 9

They are weak and as a result allow the particles to move freely. This means that gases can diffuse quickly and can be compressed easily.
