Question

What is standard room temperature in Kelvin?

Answer 1

Hint: Temperature basically can be called as a measure of the range of hotness and coldness of the object. We must know the basic relation between all three scales of temperature measurement i.e. Celsius $\left({}^{\circ }C\right)$ , Fahrenheit $\left({}^{\circ }F\right)$ and Kelvin $\left(K\right)$ . Applying the correct relation will yield the result.

Complete answer:
Standard room temperature is basically known as the most favorable temperature for survival of maximum species on the planet. It is neither too hot nor too cool. Different institutes define different standard room temperatures but the worldwide accepted range of room temperature is taken from ${20}^{\circ }C$ to ${25}^{\circ }C$ .
The Kelvin scale or Absolute temperature scale was introduced by William Thompson or Lord Kelvin in the 19th Century. It is known as the absolute temperature scale because this scale starts from absolute zero temperature, which is $-{273}^{\circ }C$ on the Celsius scale.
From the above statement we can conclude a relation between Celsius and Kelvin scale i.e.
$-{273}^{\circ }C=0K$
We can write the relation as,
$0^{\circ }C=273K$
I.e. to convert from Celsius to Kelvin scale, we need to add a value of 273 in the reading of the Celsius scale.
As standard room temperature is from ${20}^{\circ }C$ to${25}^{\circ }C$. In Kelvin scale it can be written as:
20 +273 = 293 K
25 + 273 = 298K
Range of standard room temperature in Kelvin scale is calculated from 293K to 298K.

Note:
Temperature is important to study because it has many effects in our daily life, directly and even indirectly. Standard room temperature is not the temperature of the room we are in. Mostly accepted standard temperature out of the range is ${20}^{\circ }C=293K$
