I have been attempting this problem so many times. I don't know if I am plugging in the numbers correctly but I cannot seem to get the answer correct. Please help! A patient arrives in the emergency room with a burn caused by steam. Calculate the heat, in kilocalories, that is released when 12.4 g of steam at 100. ∘C hits the skin, condenses, and cools to body temperature of 37.0 ∘C.

Question

I attempted with (100∘C-37∘C)
12.4g*63∘C*540cal/g∘C= 421848cal*1kcal/1000cal= 421.9kcal

Answer 1

I'm not sure but isn't there supposed to be specific heat involved in there ?

(Sorry if it's a silly question, but i'm still a high school student)
