High specific heat is a property of a substance that refers to the amount of heat energy required to raise the temperature of a unit mass of that substance by a certain amount. It is an important characteristic of water, which has a high specific heat compared to many other substances.
The high specific heat of water allows it to absorb a large amount of heat energy without a significant increase in temperature. This property is essential for regulating the Earth's climate and maintaining a stable environment for living organisms.
