Which statement best describes energy and matter in a closed system? a. energy and matter flow into and out of the system. b. energy can flow into and out of the system but matter cannot. c. there is no energy in a closed system; there is matter. d. energy and matter are contained within a closed system.

Option (D) is the correct answer.

Explanation:

When a system is closed then there will be no transfer of both matter and energy.

For example, when hot water is placed in a closed thermos then there will be no exchange of matter and energy from the system (thermos) to the surrounding.

Thus, we can conclude that the statement, energy and matter are contained within a closed system best describes energy and matter in a closed system.
