A.

The temperature of the water will decrease, while the temperature of the metal will increase.

B.

The temperature of the water will decrease and the temperature of the metal will also decrease.

C.

The temperature of the water will increase, while the temperature of the metal will decrease.

D.

The temperature of the water will increase and the temperature of the metal will also increase.

1 answer

The correct answer is:

C. The temperature of the water will increase, while the temperature of the metal will decrease.

When the heated piece of metal is submerged in cool water, heat flows from the metal (which is at a higher temperature) to the water (which is at a lower temperature) until thermal equilibrium is reached. As a result, the water's temperature will rise, and the metal's temperature will decrease.
