Milo is boiling water, but it is taking a long time for the water to reach its boiling point. Which of the following BEST describes why?

A: Water takes little energy to heat

B: Water has low thermal conductivity

C: Water has high heat capacity

D: Water is the universal solvent

C: Water has high heat capacity.

Water has a high heat capacity, which means it requires a relatively large amount of energy to increase its temperature. This is why it takes a long time for the water to reach its boiling point.

The BEST answer to why the water is taking a long time to reach its boiling point is C: Water has high heat capacity.

To determine the best answer, let's analyze each option:

A: Water takes little energy to heat - This is not the best answer because it implies that water can be easily heated. Although water is a good conductor of heat, it actually takes a significant amount of energy to raise its temperature.

B: Water has low thermal conductivity - This answer is also not the best because water is known to have high thermal conductivity. This means that it can transfer heat efficiently.

C: Water has high heat capacity - This is the best answer. Water has a high heat capacity, which means it can absorb a large amount of heat without a significant change in temperature. As a result, it takes longer for water to reach its boiling point compared to other substances with lower heat capacities.

D: Water is the universal solvent - This answer is unrelated to the question about the boiling time of water. Water being a universal solvent simply means that it has the ability to dissolve a wide variety of substances.

So, the best answer is C: Water has high heat capacity, which explains why it takes a long time for the water to reach its boiling point.
