Topic3:Partical Model Of Matter
SPECIFIC LATENT HEAT
measured in J/Kg
latent heat fusion
changing from solid to liquid
the energy required to change the state of 1kg of a substance without a change in temperature
latent heat in vaporisation
changing from liquid to vapour
E = m L
SPECIFIC HEAT CAPACITY
measured in J/kg celsius
temperature increases depend on material type, material mass and the energy inputted
the energy required to raise the temperature of 1kg of a substance by 1celsius
E = m c
PRESSURE IN GASES
WORK DONE
doing work on a gas will transfer energy to it
BIKE PUMP
as a pump is compressed work done on the gas so the temperature increases
pressure produces a force at right angles to the container it is in
unit of pressure is the pascal
if there is a fixed mass of gas held at a constant temperature. pV = constant
PARTICLE MOTION
molecules are in constant random motion
temperature is determined by kinetic energy of the substance
the higher the temperature the higher the kinetic energy
