One of my homework problems deals with finding the change in entropy of the surroundings using the equation
The numbers given were T=263K and delta(H)fusion=6.0*10^(3) J/mol
I know how to solve the problem, I just want to know why it is that even though the answer I got was negative, "it must be positive because of the surroundings." I was hoping someone would explain the concept behind this just so I understand. Thanks!
You didn't post all of the problem so this is the best guess I can come up with but I assume it is because delta H for the process in question is negative which makes -dH/T positive.
