  • Physics (P1)
    • Heating Houses
      • Measuring Temperature
        • A thermogram uses colour to show temperature.
          • Areas  that  are coldest are black/dark blue/purple.
            • Areas that are hottest are white/yellow.
          • Areas that are hottest are white/yellow.
        • Temperature is a measurement of hotness on  an arbitrary scale
        • When a temperature of a body increases, the average kinetic energy of the particles increases.
        • Heat is a measurement of internal energy; it is measured on an absolute scale
      • Energy Flow
        • Energy, in the form of heat, flows from a warmer to a colder body.
        • When energy flows away from
          • Energy, in the form of heat, flows from a warmer to a colder body.
      • Specific Heat Capacity
        • All substances have a property called specific heat capacity.
          • It is the energy needed to raise the temperature of 1 kg by 1.C
          • It is measured in joules per kilogram degree Celsius and differs for different materials
        • The equation for energy transfer by specific heat capacity (shc) is: energy transferred = mass x shc x temp. change.
      • Specific Latent Heat
        • It is measured in joules per kilogram (J/kg) and differs for different materials and each of the changes of state.
        • Specific latent heat is the energy needed to melt/boil 1 kg of the material.
        • The equation for energy transfer by specific latent heat (slh) is: energy transferred = mass x slh
  • It is measured in joules per kilogram degree Celsius and differs for different materials
  • Specific Heat Capacity
    • All substances have a property called specific heat capacity.
      • It is the energy needed to raise the temperature of 1 kg by 1.C
    • The equation for energy transfer by specific heat capacity (shc) is: energy transferred = mass x shc x temp. change.
