Answer:
223.15 k
Step-by-step 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.
