Convert the following temperatures to the celsius scale.
(a) 293k (b) 470k.

Explanation

(a) Temp. on Kelvin scale = Temp. on Celsius scale + 273
293 = Temp. on Celsius scale + 273
So, Temp. on Celsius scale = 293 - 273 `= 20^(@)C`.
(b) Temp. on Kelvin scale = Temp. on Celsius scale + 273
470 = Temp. on Celsius scale + 273
So, Temp. on Celsius scale = 470 - 273 `= 197^(@)C`.
