... An isolated system is one for which there are no energy transfers across the boundary. The energy in such a system is conserved , i.e., at anytime the sum is a constant but its form can change in part or in whole. E.g., a block sliding across a frictionless table is moving in an isolated system. If ...

First law of thermodynamics
... State functions are characterized by the idea that no matter what path you take to get from point A to point B, the difference between B and A remains the same. An example of how this works can be illustrated using gravitational potential energy. Say you lift a box 5 meters vertically straight up in ...
