Why work $W$ and heat $Q$ are different concepts?
It may be useful to have a look at the problem from a more quantitative perspective. Let $E$ denote the total internal energy of the system. For a thermodynamic system, it is defined as an ensemble av …

Does the entropy of an adiabatically isolated system stays the same after we decrease/increa...
And even if it is adiabatically isolated (dQ=0) shouldn't the internal energy increase and thus amount of heat in the system increase as well when we do the work on the system (move the piston to comp …

What is entropy of the universe?
It cannot decrease because of the second law of thermodynamics. It cannot stay unchanged because the universe is undergoing all kinds of irreversible processes. …
