- Thank you!!!4) Physical systems work in a “one-way street” – the amount of information we have about the state (energy state, position, velocity, etc.) of the molecules, atoms, and particles involved in general, decreases over time. A measure of the decrease of this type of information over time, or the increase in disorder, is called: energy force the adiabatic constant entropy workIn each cycle of its operation, a refrigerator removes 13 J of heat from the inside of the refrigerator and releases 36 J of heat into the room. How much work per cycle is required to operate this refrigerator? J
