Is water made of atoms or molecules?
Waters is made of molecules. Each of those molecules contains 3 atoms.
Why is evaporation greater over warm waters?
The movement of molecules increase when the temperature increase; some molecules at the water surface can escape as a gas.
What does it mean when salfuric acid has a specific gravity of 1.8?
Specific gravity of sulfuric acid = 1.8 specific gravity is the ratio of the density of a substance to the density of water (waters density in the denominator). So this means the density is 1.8 g/mL
What causes evaporation of Earths waters to occur?
The cause of evaporation is the continuous movement of molecules at the surface of a liquid; gaining more energy they can escape in the air. Temperature favors this process.
What causes waters low vapor pressure?
Water molecules hydrogen bond which is a very strong intermolecular force. As a result the water molecules are held together well. Vapor pressure is dependent on how well molecules are intermolecularly bonded to one another. If a substance like water is held together well then it will have a low vapor pressure because a larger amount of energy is required to break these intermolecular bonds. Compare water to carbon tetrachloride which is non polar and can't hydrogen bond. Because it only has weak London dispersion forces to hold the molecules together it will have a higher vapor pressure. This is because only a small amount of energy is required to break the intermolecular bonds causing the CCl4 to vaporize.

What is waters specific gravity?
1
Waters high specific heat is mainly a consequence of?
Water has a high specific heat capacity because it is a relatively light molecule (18 grams per mole). The specific heats of molecules are all about the same on a per-molecule basis, especially at higher temperatures. This is called the law of Dulong and Petit. At low temperatures, it gets more complicated because the vibrations of molecules are quantized. When specific heats are measured on a per-gram basis, lighter molecules have higher specific heats. For example, the specific heat of hydrogen (H2), which has a molecular weight of 2 grams per mole, is much higher than that of water. Liquid water has a higher specific heat than most other liquids (such as alcohols) because its molecules are lighter.

How does oils density compare to waters density?
Oil is heavier than water so it sinks to the bottom.
What means that a large amount of energy is required to change the waters temperature?
Specific heat
Is gravity a wave or a particle?
Neither. It's a force. A force of space that acts similar the the pressure of water exerted on an object when in deep waters. Space is the ultimate of deep waters.
Sodium perborate trihdrate same as sodium perborate tetrahydrate?
Very similar, but not identical. The term "hydrate" means that there are water molecules associated with the sodium perborate. In the first case, the "tri" means that there are 3 water molecules, and in the second case, the "tetra" means there are 4 water molecules.If you are making an aqueous solution of this material, it will make no difference in its properties (if not, it is possible it could matter that there is extra waters, I'm not sure about that). One thing that certainly does change is the molecular weight -- make sure to calculate the molecular weight properly including the right number of waters.
What is the Number of water molecules bound per formula unit of nickel II nitrate?
There are four water molecules bound to Sodium Chromate
What are waters bonds?
Water has two main bonds: hydrogen bonds between other water molecules, and a covalent bond between hydrogen and oxygen.
What is the plural of water?
The singular noun, water is an uncountable noun, a word for a substance.The noun 'waters' is the plural. The plural form for many uncountable nouns has specific contexts. The plural form 'waters' is a word for an area of seawater bordering on and under the control of a country, territorial waters (sailing Spanish waters); water from a particular source (the waters at Baden-Baden); or used for a particular type of situation (navigating troubled waters).
Which of the following explains most specifically the attraction of water molecules to one another?
The property of adhesion explains waters interactions with itself and surroundings.
