Question

In the definition of a Universe / System setup, the system and the universe energy changes and both will equal zero! True / False

Answer 1

Given statement is True

Entropy of universe increases. It implies that the energy always flows downhill. Energy flows from hot region to cold region. In thermodynamics, we assume universe into a system and its surroundings.

In this setup, the the energy flows from sytem to surrounding or sounding to system vice-versa. when the system gives off energy the surroundings gain energy, vice versa. The two changes are equal in size but opposite in sign. However, the total change in energy of the univese is zero in accordance with conservation of energy.
