Question

water has a high specific heat capacity. what does this mean? the temperature of water changes very slowly. the density of water changes very quickly.

Explanation:

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. A high specific heat capacity means a substance (like water) needs a large amount of heat to change its temperature, so its temperature changes slowly. Density and specific heat capacity are different properties, so the option about density changing quickly is incorrect.

Answer:

The temperature of water changes very slowly.
