Homework Statement
The temperature difference between the inside and the outside of a home on a cold winter day is 57.0°F.
express in C and in K
Homework Equations
Tf = (9/5) delta Tc
Tc = Tk - 273.15
The Attempt at a Solution
I used the first equation to find that the temp difference in C is 31.67
I then thought that you added 273 to that temperature to find Kelvin but on my homework the answer key said that the correct answer is 31.67K ... i don't understand how the two can be equal?
