Question

Convert the following temperatures to the Celsius scale.
(a) 293 K
(b) 470 K

Answer 1

Hint: The temperature is going to be measured with various units. Two among them are Celsius and Kelvin.
There is a relation between Celsius scale and Kelvin.
The relationship between Celsius and kelvin is as follows.
Temperature in Kelvin (K) = Temperature in $^{o}C$ + 273

Complete step by step answer:
- In the question they gave the temperature in Kelvin.
- Now we have to convert the given temperature to $^{o}C$ .
- The formula to convert the $^{o}C$ to Kelvin is as follows.
Temperature in $^{o}C$ = Temperature in Kelvin (K) – 273
Here $^{o}C$ = degree Celsius
K = Kelvin
(a) 293 K = Temperature in Kelvin
Temperature in $^{o}C$ = 293 K – 273 = 20 $^{o}C$
Therefore 293 K = 20 $^{o}C$
(b) 470 K = Temperature in Kelvin
Temperature in $^{o}C$ = 470 K – 273 = 197 $^{o}C$
Therefore 470 K = 197 $^{o}C$

Additional information:
- The simple difference between these Kelvin and Celsius scales is zero points (initial point) of the thermometer.
- Kelvin is the SI unit to measure temperature.
- There is one more unit to measure the temperature that is degree Fahrenheit heat (F).
- Numerically Kelvin value is higher when compared to degree Celsius scale.

Note: The Kelvin scale is related to temperature. It is the thermodynamic scale based on an ideal heat engine that monitors the Carnot engine. One unit upsurge in the Kelvin scale is the same as one-degree upsurge in Celsius scale.
