GENERAL HISTOLOGY

Detailed explanation-1: -When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.

Detailed explanation-2: -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. Water has the highest specific heat capacity of any liquid.

Detailed explanation-3: -Hydrogen bonds pull the molecules together to form a dense structure. The molecules want to stay together and hold up the ice or the bug. Surface tension gives the water enough structure to hold somethings on top. If you break the surface tension, the item will sink.
