Why water is a poor conductor of heat answer for grade 7?

Water is a poor conductor of heat because its molecules are held together by hydrogen bonds, which makes it difficult for them to transfer energy quickly. When heat is applied, the water molecules absorb energy but do not easily pass it on to neighboring molecules. This means that water can warm up or cool down slowly compared to materials that are better conductors, like metals. As a result, water is often used as a coolant in various applications.
