4F.3 Reversible Process

Postby KDang_1D » Tue Feb 11, 2020 12:08 am

Calculate the change in entropy of a block of copper at 25ºC that absorbs 65J of energy from a heater.


Why can we assume that this is a reversible process?

Maybe it's because the heat can be given off from the copper block?

We can approximate here and assume that it is a reversible reaction because the surroundings are so large that any change in heat will have little to no effect on the the surroundings.
