Question

According to the law of conservation of energy, which statement must be

true?
A. Energy that is transferred cannot be transformed into a different
type of energy.
O B. The total energy in a system can only decrease over time.
OC. A system cannot take in additional matter.
OD. The total energy of a system can increase only if energy enters the
system

Answer 1

D. The total energy of a system can increase only if energy enters the

system

energy must be conserved--it cannot be created or destroyed.

so, if the energy of a system increases, that energy must have come from somewhere

hope this helps!!
