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 is the lowest posible temperature, and at this point the molecules have zero speed which results in zero kinetic energy

q2 A) i) Tk = Toc + 273 = 20+273 = 293k

ii) 150+273 = 423k

iii) 1000+273 = 1273k

b) i) Toc = Tk - 273 = 300 - 273 = 27 degrees

ii) 650 - 273 = 377 degrees

iii) 1000 - 273 = 727 degrees
