Quizplus · Accepted Answer

Water is a polar molecule, which means that the atoms within each molecule carry partial charges. This polarity allows it to dissolve a wide variety of different substances and makes it a good solvent. It's referred to as a universal solvent because it is able to dissolve more substances than any other liquid.
All substances, including water, become less dense when they are heated and more dense when they are cooled. So, if water is cooled, it becomes more dense and forms ice. Water is one of the few substances whose solid state (ice) can float on its liquid state.
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. Specific heat is defined as the amount of heat that one gram of a substance must absorb or lose to change its temperature by one degree Celsius.
There are 3 different forms of water, or H2O: solid (ice), liquid (water), and gas (steam).
