5.14

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

Converting Centigrade to Kelvin
TK = ToC + 273

Converting Kelvin to Centigrade
ToC = TK - 273

TK = Temperature in Kelvin [K]

ToC = Temperature in Degrees Centigrade [oC]

1. T absolute zero (- 273 degrees centigrade) is when kinetic energy is at zero and the particles are not moving, you cannot go past this point as the particles cannot lose anymore energy as there is non left. 2. a) 20°C = 293K, ii) 150°C = 423K, iii) 1000°C = 1273°C
b) 300K = 27°C ii)650K= 377°C iii) 1000K = 727°C
