Answer:

The correct answer is D)high specific heat

Explanation:

The specific heat indicates the amount of heat required to raise the temperature of a substance in 1 unit of temperature. The specific heat of water is around 4.18 J/g.°C. That means that 1 gram of water is able to retain a high amount of heat (4.18 J) when the temperature is raised to 1°C. Compared with other substances, this specific heat capacity is higher. Thus, water is a good choice for use in a heat exchanger.
