Explain why water has a high specific heat capacity and it advantages

Water has a high specific heat capacity because a large amount of thermal energy needs to be absorbed in order to break the hydrogen bonds among water molecules before the individual water molecules can begin to move about more freely and therefore, causing an increase in temperature. A high specific heat capacity allows water to stabilize the internal temperature of organisms and environments such as large bodies of water like oceans and ponds.

Explain why ice floats

At O˚C, water molecules become locked into a crystalline lattice structure; each water molecule bonded to four other molecules through hydrogen bonding. This is the solid state of water called ice. The hydrogen bonds keep the water molecules far apart enough to give ice a density of about 10% less than that of liquid water. The crystalline structure provides a larger volume for the same amount of liquid water molecules. Therefore, ice is less dense compared to liquid water and ice floats on liquid water.
