properties of matter

• As the temperature of the gas increases the mean kinetic energy of the particles also increases.
• a lower area = a higher pressure
• a higher temperature = a higher pressure
• a lower volume = a higher pressure
• The temperature of a substance is a measure of the mean kinetic energy of its particles.
• solid to a liquid (fusion)
• liquid to a gas (vaporisation)
• a higher force = a higher pressure
• phase changes:

  A) melting

  B) vaporisation

  C) gas

  D) liquid

  E) solid
