Solids Liquids and Gases

Question 1

Solids state of matter

Answer 1

• Particles in a solid are close together, arranged in a regular pattern and vibrate on the spot, so solids have a fixed shape and cannot be compressed.

Question 2

Liquids state of matter

Answer 2

• Particles in a liquid are close together, randomly arranged and moving around, so liquids are incompressible but can flow.

Question 3

Gases state of matter

Answer 3

• Particles in a gas are far apart, randomly arranged and moving in all directions, so gases expand to fill a container and can be compressed.

Question 4

Liquid to Gas

Answer 4

• Liquid to gas is evaporating or boiling, and the reverse is condensing.

Question 5

Sublimation

Answer 5

Sublimation is where a solid turns straight to a gas

Question 6

Compressing a gas

Answer 6

Compressing a gas will turn it into a liquid.

Question 7

Solubility of Solids

Answer 7

a solvent is soluble if it dissolves in a given solvent
a solvent is insolvable if it does not dissolve in a solvent
generally solids become soluble at high temperatures
a solubility is a curve graph of solubility against temperature

Question 8

Solubility of gases

Answer 8

• The solubility of a gas depends on the temperature and pressure.
As the pressure increases the more gas dissolves
as the pressure increases gases tend to become less soluble
