5.14 The Kelvin Scale

5.14 describe the Kelvin scale of temperature and be able to convert between the Kelvin and Celsius scales

Describe: The Kelvin scale begins at -273°C and the intervals between Centigrade and Kelvin are equal (i.e. ΔK = Δ°C)

Converting:
To Kelvin: Kelvin = Centigrade + 273
To Centigrade: Centigrade = Kelvin – 273

Examples
Convert these temperatures

1. 20°C = 20 + 273 = 293K
2. 150°C = 150 + 273 = 423k
3. 300K = 300 – 273 = 27°C
4. 650K = 650 – 273 = 377°C
