Syllabus Points — Temperature

14.1 Thermal equilibrium

  1. understand that (thermal) energy is transferred from a region of higher temperature to a region of lower temperature
  2. understand that regions of equal temperature are in thermal equilibrium

14.2 Temperature scales

  1. understand that a physical property that varies with temperature may be used for the measurement of temperature and state examples of such properties, including the density of a liquid, volume of a gas at constant pressure, resistance of a metal, e.m.f. of a thermocouple
  2. understand that the scale of thermodynamic temperature does not depend on the property of any particular substance
  3. convert temperatures between kelvin and degrees Celsius and recall that T/K=θ/°C+273.15T/K = \theta/°C + 273.15
  4. understand that the lowest possible temperature is zero kelvin on the thermodynamic temperature scale and that this is known as absolute zero

14.3 Specific heat capacity and specific latent heat

  1. define and use specific heat capacity
  2. define and use specific latent heat and distinguish between specific latent heat of fusion and specific latent heat of vaporisation
