14. Temperature
14.1 Thermal equilibrium
- understand that (thermal) energy is transferred from a region of higher temperature to a region of lower temperature
- understand that regions of equal temperature are in thermal equilibrium
14.2 Temperature scales
- 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
- understand that the scale of thermodynamic temperature does not depend on the property of any particular substance
- convert temperatures between kelvin and degrees Celsius and recall that T /K = θ/°C + 273.15
- 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
- define and use specific heat capacity
- define and use specific latent heat and distinguish between specific latent heat of fusion and specific latent heat of vaporisation
