b) Absolute scale

b) absolute scale of temperature (i.e. the thermodyanmic scale) that does not depend on property of any particular substance

c) temperature measurements both in degrees celsius (°C) and kelvin (K)

d) T(K) ≈ θ(°C) + 273

triple point = the temperature and pressure where all of a substance’s states of matter are in thermal equilibrium

celsius scale

• two definable temperature points

  • freezing point of pure water = 0°C

  • boiling point of pure water = 100°C

absolute temperature scale

• two definable temperature points

  • absolute zero = 0K

  • triple point of pure water = 273K

T = θ + 273

• temperature (K) = temperature (°C) + 273
