Question

Which of the following situations would result from water having a high specific heat?

Answer 1

Answer: D. Sweat evaporating from the skin cools the body because so much heat is removed while it evaporates

Explanation: Specific heat is the amount of hat required to raise the temperature of 1 gram of water through $1^0C$

Thus a substance having high specific heat would absorb more heat to raise the temperature.

A. When cooking pasta, the water boils really fast cannot be true as water having high specific heat would require more heat and thus will boil slow.

B. The ocean changes temperatures quickly as the seasons change will not be true as temperature change will be slow due to high specific heat of water.

C. It doesn't take more than a day or two in the summer time for the swimming pool to heat up to a comfortable temperature as the heat requirement is more due to high specific heat of water.

D. Sweat evaporating from the skin cools the body because so much heat is removed while it evaporates is true as more heat will be absorbed by the body to vaporize water and thus produces more cooling.

Answer 2

D. Sweat evaporating from the skin cools the body because so much heat is removed while it evaporates
