particle model of matter

• What is Boyle's law?

  States that for a fixed mass of - as at constant temperature (T) the pressure (P) and volume (V) are inversely proportional
• What is the internal energy of a substance?

  Total kinetic energy and the potential energy of all the particles that make up a system
• What's the specific latent heat of a substance?

  The amount of energy required to change the state by 1kg of the substance with no change in temperature
• Explain why the temperature of a tire increases when you pump the tyre?

  • as you push down on the bike pump, work is done
  • energy is transferred to the gas by the force
  • the internal energy of the gas increases, which leads to a temperature increase
• What is density?

  How much mass (particles) there is in a given volume (space)
