· 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]

Q1) Absolute zero is the lowest temperature possible where there is no heat in the particles to make it have kinetic energy. This means that at this temperature, -273 oC, the particles stop moving completely and do not even vibrate. If you go beyond absolute zero, there will be no change and nothing will happen. Q2)
a)
i) Tk = Toc + 273
Tk = 293 K
ii) Tk = Toc + 273
Tk = 423 K
iii) Tk = Toc + 273
Tk = 1273 K

b)
i) Toc = Tk - 273
Toc = 27 oC
ii) Toc = Tk - 273
Toc = 377 oC
iii) Toc = Tk - 273
Toc = 727 oC
