· 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. How does kinetic theory explain the idea of absolute zero? Absolute zero is the point where no heat can be removed from the system. Using kinetic theory, we can explain that at absolute zero no particles should have any energy to move since there is no heat. 2. a) Convert these temperatures from Degrees to Kelvin:
1. 20 --> 293
2. 150 --> 423
3. 1000 --> 1273
b) Convert these temperatures from Kelving to degrees: 1. 300 --> 27
2. 650 --> 377
3. 1000 --> 727
