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]

1. To get to this temperature, the object must basically have no heat energy, and since heat is the energy given off when particles have increased kinetic energy, to get to absolute zero, the kinetic energy between particles have to stop. Which means the kinetic energy between them have to stop too. 

2a. 20c = 293 K 

b. 150c+273 = 323K

c. 1273k 

3a.  27c 

b. 377c 

c.727c
