Detailed explanation-1: -Explanation: water has the highest specific heat (1.0). Because water has such a high specific heat it will be able to retain (hold) heat much longer than a substance with a lower specific heat.
Detailed explanation-2: -Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
Detailed explanation-3: -Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg−1⋅K−1 at 20 °C; but that of ice, just below 0 °C, is only 2093 J⋅kg−1⋅K−1.
Detailed explanation-4: -However, water is an exception due to the strong hydrogen bonding present in its liquid state. These forces are stronger than the forces of the solid state. That’s why specific heat capacity of water > ice > steam. However, water is an exception due to the strong hydrogen bonding present in its liquid state.
Detailed explanation-5: -Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.
