Detailed explanation-1: -Covalent bonds give water a low HIGH heat capacity.

Detailed explanation-2: -Covalent bonds give water a low heat capacity. 4. A hydrogen bond is stronger than a covalent bond.

Detailed explanation-3: -Water has a high specific heat capacity-it absorbs a lot of heat before it begins to get hot.

Detailed explanation-4: -Physical change cannot break covalent bonds, which are extremely strong. As a result, heating a liquid does not break any covalent bond.

Detailed explanation-5: -The hydrogen atoms are not only covalently attached to their oxygen atoms but also attracted towards other nearby oxygen atoms. This attraction is the basis of the ‘hydrogen’ bonds. The water hydrogen bond is a weak bond, never stronger than about a twentieth of the strength of the O-H covalent bond.
