Chapter 14 - Heat - Misconceptual Questions: 12

Answer

Choice A.

Work Step by Step

We’re told that the two equal-mass liquids absorb the same amount of heat. Because the liquids have the same mass, equation 14-2 shows that the heat transfer is proportional to the specific heat of each liquid multiplied by its own change in temperature. The liquid with the higher specific heat must have undergone the smaller temperature change, i.e., it is cooler.
