High specific heat capacity stabilizes water's temperature

Steps:

• Large volumes of water resist temperature changes due to requiring substantial heat energy for warming.
• Specific heat capacity measures heat needed to raise 1 kg of substance by 1°C; water's is 4180 J/kg°C, higher than most substances.
• When ambient temperature rises, heat transfers slowly to water, keeping its temperature constant.
• This property explains thermal regulation in oceans and lakes.

Why C is correct:

• High specific heat capacity means water absorbs large amounts of heat with minimal temperature rise, directly maintaining constant temperature per the definition of specific heat (q = mcΔT).

Why the others are wrong:

• A: Latent heat of vaporization relates to phase change (liquid to gas), not temperature maintenance without evaporation.
• B: Water molecules form up to four hydrogen bonds, but this contributes indirectly to properties like specific heat, not the direct explanation.
• D: Evaporation cools surfaces via latent heat loss, but applies to small amounts or phase change, not large volumes maintaining temperature.

Final answer: C
