Find the value of $-197^{\circ} \mathrm{C}$ temperature in Kelvin.

Find the value of $-197^{\circ} \mathrm{C}$ temperature in Kelvin.
  1. $47 \mathrm{~K}$
  2. $76 \mathrm{~K}$
  3. $470 \mathrm{~K}$
  4. $760 \mathrm{~K}$

Solution

$\begin{aligned} & \mathrm{T}_{(\mathrm{K})}=\mathrm{T}\left({ }^{\circ} \mathrm{C}\right)+273 \\ & =-197^{\circ} \mathrm{C}+273 \\ & =76 \mathrm{~K} \end{aligned}$
