Study Notes

Gas Properties

  • Temperature and average kinetic energy of particles in a gas are directly proportional.
  • Standard conditions for temperature and pressure (STP) are 0°C and 1 atm.
  • If temperature is kept constant and volume of a gas is doubled, pressure is reduced to 1/2 of the original value.
