Question

A difference of $1^{\circ }C$ is _____ as the difference of $1K$.

Answer 1

We know that $K=273{+}^{o}C$
So if we will increase temperature by $1^{o}C$ then in Kelvin temperature will also increase by 1.
For example let say temperate is ${}^{o}C=27$
So in Kelvin $T=27+273=300K$
Now if we increase the temperature by $1^{o}C$, that is $27+1=$ ${28}^{o}C$
Now in Kelvin, $T_1=28+273=301K$
So in Kelvin, the increase in temperature is also 1.
