Question

Why does water cool off more slowly?
Because of its density
Because of its color
Because of its salinity
Because of its hydrogen bonds

Answer 1

Water cools off more slowly primarily because of its hydrogen bonds. The high specific heat capacity of water, which means it can absorb a lot of heat without a significant change in temperature, is largely due to the hydrogen bonds between water molecules. These bonds require energy to break, so when water is heated, a lot of energy goes into breaking these bonds rather than increasing the temperature, and similarly, when water cools down, it retains heat longer as the bonds reform.

So, the correct answer is: **Because of its hydrogen bonds.**
