Question

select the correct answer. an engineer designing a new type of engine needs a liquid that can be heated and cooled quickly with as little exchange of energy as possible. which property should the engineer primarily look for in the liquid? a. low thermal conductivity b. low specific heat capacity c. high reactivity d. high internal energy e. high density

Explanation:

The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of a unit - mass of the substance by one degree Celsius. A liquid with a low specific heat capacity will require less energy to change its temperature, meaning it can be heated and cooled quickly with little energy exchange. Thermal conductivity is related to the rate of heat transfer through a material, not the energy needed to change the temperature of the material itself. High reactivity, high internal energy, and high density are not directly related to the ease of heating and cooling with little energy exchange.

Answer:

B. low specific heat capacity
