gasses and pressure

• TEMPERATURE AND PRESSURE

  temp and pressure are directly proportional

  both increase when volume is constant

  energy is transferred from heat energy to kinetic energy

  kinetic energy and speed are related {Ek=½mv2}
• TEMP& PRESSURE

  average KE increases so average speed of particles increase

  therefore more frequent collisions

  frequency of collisions causes a rate of change of momentum
• rate of change of momentum

  F= change in momentum/time
• temp & pressure

  this causes a force

  pressure is exerted by the gas because

  pressure = force/area
