Answer:
Water is polar in nature and forms hydrogen bond.
Step-by-step explanation:
Water forms hydrogen bonds even when it is at its normal state. This is so because water is highly polar in nature.Being polar in nature means , the molecules or atoms with in any compound arrange themselves in a polarized state where one group of atoms or molecules becomes positively charged while other group of atoms or molecules becomes negatively charged.
Therefore, more heat is required to break these hydrogen bonds in water as compared to any other molecule of similar shape or size.
