The correct answer is D. One with a high heat capacity

Explanation:

In chemistry and related fields, the heat capacity of a liquid refers to the amount of heat that is required for the liquid to change its temperature, in this way, substances with a low heat capacity will become hotter or colder in a short time because the molecules in them are more susceptible to heat and retain it.

This implies, in the case presented the liquid that would be most difficult to raise or lower the temperature of is one with a high heat capacity because this factor rather than density is the one that affects how fast a liquid loses or gains heat. Also, if a liquid has a high heat capacity as it occurs with water it takes some time for it to experience changes in temperature.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
