Question

300k temperature change in Celsius.

Answer 1

Let's denote $t$ - temperature in Celsius, $T$ - tempetarure in Kelvin.

The connection between these units is $T = t + 273.15$ and as following $t = T - 273.15$

If $\Delta T = T_2 - T_1 = 300\; K$, then

$\Delta t = t_2 - t_1 = T_2 - 273.15 - (T_1 - 273.15) =$

$= T_2 - 273.15 - T_1 +273.15 = T_2-T_1 = \Delta T$.

So, $\Delta t = \Delta T = 300^\circ C$.

Answer: $\Delta t= 300^\circ C$.
