. Convert the following temperatures to Celsius scale:


(a) 300 K

(b) 573 K

 

Best Answer

Ans. (a) Kelvin is the SI unit of temperature. To change a temperature on the Kelvin scale to the Celsius scale you have to subtract 273 from the given temperature, and to convert a temperature on the Celsius scale to the Kelvin scale you have to add 273 to the given temperature.

Temp. on Kelvin scale = Temp. on Celsius scale + 273

300 K = Temp. on Celsius scale + 273

Temp. on Celsius scale=300 - 273 = 270C

Thus, a temperature of 300 K on Kelvin scale is equal to 270C on Celsius scale.

(b) Kelvin is the SI unit of temperature. To change a temperature on the Kelvin scale to the Celsius scale you have to subtract 273 from the given temperature, and to convert a temperature on the Celsius scale to the Kelvin scale you have to add 273 to the given temperature.

Temp. on Kelvin scale = Temp. on Celsius scale + 273

573 = Temp. on Celsius scale + 273

And, Temp. on Celsius scale= 573 - 273 = 300°C

Thus, a temperature of 573 K on Kelvin scale is equal to 300°C on Celsius scale.
