Question

Why does the temperature of ocean water remain relatively constant, despite large fluctuations in air temperature? A) Ocean water has a high concentration of dissolved salts B) Ocean water has a high specific heat C) Ocean water is a major component of organisms D) Ocean water exists in the form of water vapor

Answer 1

The answer is B. The specific heat means the heat amount the substance needs to absorb when the temperature increases 1℃. The high specific heat means that it needs a huge amount of heat when increase just 1℃. For A, the dissolved salts can help decrease the freezing point.
