Concept explainers
(a)
Interpretation:
The given temperatures have to be converted to Celsius scale.
Concept Introduction:
Temperature is the measure of heat of a substance. Temperature is measured in Celsius scale. But usually represented in Kelvin scale. The temperature in Celsius scale can be converted into Kelvin scale by adding 273.15 to it.
From the above equation Celsius temperature can be found out by rearranging the equation. The equation for finding temperature in Celsius scale from Kelvin scale is,
