Question

Convert the following temperatures to Celsius scale:
(i) 300 k
(ii) 573 k

Answer 1

The relation between Kelvin scale and Celsius scale is given by a mathematical equation which is $K = {}^0C + 273$, where the temperature in Kelvin is calculated by adding temperature in degree Celsius with 273.

Complete step by step answer:
The Celsius scale is known as the centigrade scale where the temperature scale is based on 0 degree for freezing point temperature and 100 degree for the boiling point of water. The Celsius scale is first observed by Swedish physicist, engineer Anders Celsius.
The Kelvin scale is also known as the absolute scale where temperature exists is much colder than the freezing point of ice 0 degree Celsius on the Celsius scale.
Kelvin wisely proposed that temperature from the ice point to the steam point is defined as the 100 degrees which is said as the centigrade scale. All the thermometers consists of the scale from which temperature can be known. This scale is called temperature scale.
In the Kelvin scale, the zero point is 273.15 below this temperature is the Celsius scale.
The relation between Kelvin scale and Celsius scale Is given by a mathematical equation which is shown below.
$K = {}^0C + 273$
K is the temperature on the Kelvin scale.
${}^0C$ is the temperature in degrees Celsius.
To convert temperature in kelvin into Celsius scale, the equation is written as shown below.
${}^0C = K - 273$
(1) 300 K
$\Rightarrow {}^0C = 300 - 273$
$\Rightarrow {}^0C = 27^\circ C$
(2) 573 K
$\Rightarrow {}^0C = 573 - 273$
$\Rightarrow {}^0C = 300^\circ C$

Note:
Don’t get confused while converting the temperature in kelvin to degree Celsius as the equation is just revered. The value of Celsius temperature can be negative but Kelvin goes down to zero (it does not have negative value)
