Temperature & Heat

Temperature
1. Hotness or coldness of a body
2. Units
  1. Kelvin (K)
  2. degree Celcius
  3. Farenheit
3. Thermometric property
  1. Physical property that changes measurably with temperature
  2. Calibration curve
4. Scalar quantity
Heat
1. Energy due to the movement of molecules within the body
2. Scalar quantity
3. Joules (J)
Heat Capacity (C)
1. The amount of heat required to raise the temperature of a body by 1 K
2. J/ K
3. Specific heat capacity (c)
  1. Amount of heat required to raise the temperature of 1kg of a substance by 1 K
  2. J/ kg/ K
  3. Q = mcΔθ
    1. m = mass of body
    2. c = specific heat capacity
4. Q = CΔθ
  1. Q = Energy
  2. Δθ = Change in temperature
  3. C = Heat capacity
Latent Heat
1. Amount of heat required to change a body's state, without a change in temperature
2. Joules
3. Specific latent heat (l)
  1. Amount of heat required to change the state of 1 kg of a substance without a change in temperature
  2. Specific latent heat of fusion
    1. Solid to liquid
  3. Specific latent heat of vaporisation
    1. Liquid to gas
  4. Q = ml
Heat transfer
1. Conduction
  1. No overall movement of the substance
2. Convection
  1. Through movement of circulating fluid
3. Radiation
  1. Via electromagnetic waves
