Increasing the pressure of a gas

• Work is the transfer of energy by a force
• Doing work on a gas increases the internal energy of the gas and can cause an increase in the temperature of the gas
• The temperature of air inside a bike pump increases when it is pumped because

  • Work is done on a gas when it is compressed
  • doing work on a gas increases it’s internal energy, so also increases the average kinetic energy of the molecules
  • temperature increases with an increase of average kinetic energy
