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

Converting Centigrade to Kelvin
T_K = T_oC + 273

 

Converting Kelvin to Centigrade
T_oC = T_K - 273

 

T_K = Temperature in Kelvin [K]

T_oC = Temperature in Degrees Centigrade [^oC]

Q1:  Absolute zero (-273 degrees) is when the particles CANNOT move anymore, they have no more kinetic energy.

Q2: i) 20+273 = 293K     ii) 150+273 = 423K     iii) 1000+273 =1273K       

Q3: i) 300-273 =  27degrees    ii) 650-273 =  377degrees    iii) 1000 - 273 = 727 degrees
