Question

1. Convert the following temperature to Celsius scale.

(A)293 K

(B)470K

2. Convert the following temperature to kelvin scale.

(A)25degree C

(B)373degree C

Answer 1

Conversion to the Celsius (or Centigrade scale) is very simple: just subtract 273.15 ° to any Kelvin temperature.

K = °C + 273.15
°C = K - 273.15

K = temperature, Kelvin

°C = temperature, degrees Celsius (Centigrade)

1

A)

293K in °C => 293-273.15 = 19.85°

B)

470K in °C => 470-273.15 = 196.85°




2

K = °C + 273.15

A)

25 °C in K => 25+273.15 = 298.15K

B)

373 °C in K => 373+273.15 = 646.15K
