Question

1. if substance a has a higher specific heat capacity than substance b, which of the following is true? substance a dissolves polar molecules better than substance b. substance b freezes at a higher temperature than substance a. substance b changes temperature more slowly than substance a. substance a requires more energy to change its temperature than substance b.

Explanation:

Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by one - degree Celsius. A substance with a higher specific heat capacity needs more energy to change its temperature compared to a substance with a lower specific heat capacity. Solubility of polar molecules and freezing point are not related to specific heat capacity. Also, a substance with higher specific heat changes temperature more slowly, so substance A (with higher specific heat) requires more energy to change its temperature than substance B.

Answer:

Substance A requires more energy to change its temperature than substance B.
