Molecules with stronger intermolecular forces will have a greater melting and boiling point than those with weaker intermolecular forces. Due to water's polarity it exhibits dipole-diplole interactions between molecules with the positively charged hydrogen atoms from one water molecule aligning with the negatively charged oxygen atoms. These forces are strong enough to keep water in its liquid state up to 100o C.
polarity! Polarity is the reason that water and oil do not mix
Water cohesion causes surface tension related to solubility. Polarity is also related to solubility in that polar substances dissolve better in polar solvents, such as water.
Water is a liquid at room temperature and normal pressure.
You can you change liquid water into a solid (ice) by lowering its temperature. You can you change liquid water into a gas (water vapor) by raising its temperature.
Alcohol, water, oil, and mercury come to mind.
Water's polarity lets it stay liquid at room temperature. Most molecules of water's size are gas, but because water molecules attract each other they are connected by polar bonds that cause it to be liquid. Also, its polarity make it a solvent. Molecules connected ionically get separated when introduced into water. This is why salt disolves in water, literally because the water breaks up the ionic bond between the Sodium and Chloride. Also, water's ionic nature is what lets it move up the roots and stems of plants and into the leaves. This process is similar to how if you place the edge of a paper towel in water the water moves up the paper towel inspite of gravity.
Liquid
No it is a liquid
no
Water is liquid at room temperature, but it is not an element. Water is a combination of two elements, Hydrogen and Oxygen, with the formula H2O. Water is not an element. Mercury (Hg) is an element which is liquid at room temperature.
Sure. Boiling point is related to pressure. Increase the pressure and boiling will occur at a higher temperature.
Because of the polarity of water, it exhibits a greater cohesion and adhesion to itself and other substances. This means that water holds on to itself more firmly than it does other substances.
