Question

-54 °c converted to kelvin is k.

Answer 1

`T_([K])=t_([^oC])+273.15\\\\t_([^oC])=-54\\\\subtitute\\\\T_([K])=-54+273.15=219.15\approx219\\\\Answer:\boxed{-54^oC=219.15K\approx219K}`

Answer 2

223.15 k

Explanation:

To convert from Celsius to Kelvin you just have to add 273.15 to the Celsius to get the grades in Kelvin.

So the Formula would be:

K=Cº+273.15

Now you just put the values given into the formula and it would look like this:

K= -50+273.15

K=223.15

And your answer would be that -50º C is in 223.15 kelvin.
