उत्तर
Will absorb heat

Water is a good heat absorber. It absorbs heat slowly and releases it slowly, which does not cause sudden changes in temperature. This is why the water of seas and lakes heats up slowly during the day and cools down slowly at night. This feature helps in maintaining climatic balance.
