This question is from the princeton review gen chem book and I cant figure out why this is the answer:
For a perfectly insulated system, what are the values of ΔE internal and q if w = +100 J .
The answer is:
ΔE = + 100 J and q = 0 .
Now, I understand why q = 0 , as this is the definition of a adiabatic process.
However, I thought that during adiabatic processes, since q = 0, ΔE internal = -w .
As w = + 100 J , wouldnt the answer be:
ΔE = - 100 J and q = 0 ?
Thanks!
