In a storage-type heat exchanger, when the hot fluid flows
through the matrix, the temperature of the entire matrix rises to the hot-fluid
temperature. When cold fluid flows through it, its temperature drops to the
cold-fluid temperature. Check the appropriate answer for this phenomenon to
occur.

(a) It depends on the matrix NTU. (b) true (c) false

(d) It depends on the temperature levels.
