With
respect to the first law of thermodynamics, which of the following statements
is the most relevant?
There is a natural tendency for any system to
degenerate into a disordered state.
Energy
can be created or destroyed depending on the source of input.
A
process that involves transfer of heat energy is irreversible.
Energy
is always conserved.
Energy
is always conserved.
First law of thermodynamics states
that the change in internal energy of a system is equal to the heat added to
the system minus the work done by the system. This law is related to conservation of energy.
Hence,
the correct option is (D).
