Convert the following temperature to the Celsius scale. [2 MARKS].
(a) 293 K (b) 470 K
Solution : 1 Mark each
(a) Temperature in Celsius scale = Temperature in Kelvin scale – 273
⇒ 293 K = 293 K – 273
= 20°C
(b) Temperature in Celsius scale = Temperature in Kelvin scale – 273
⇒ 470 K = 470 K – 273
= 197°C
