Correct Answer: it has high specific heat


Solution : The correct option is it has a high specific heat.

Water is used in a hot water bag because it has a high specific heat capacity, which allows it to absorb and maintain a substantial quantity of heat energy while only undergoing a minor temperature increase. When put in a hot water bag, this property allows water to give sustained and progressive warmth, making it perfect for medicinal and warming purposes.
