Pressure

• Work on a Gas

  • Work is the transfer of energy by a force
  • Doing work on a gas involves a transfer of energy
  • This increases its internal energy and can also cause an increase in the temperature
  • Work can be done on a gas by compression
  • A force is used to push a piston by a certain distance
  • This decreases the volume of the gas
  • The molecules move around faster and therefore have a higher kinetic energy
  • This increase in kinetic energy increases its temperature
