Properties of water

Why is water considered a molecule

Electrons are being shared in a covalent bond between the hydrogen and oxygen

Is polar

Hydrogen bond

It is a week force of attraction between the positively charged hydrogen and a polar molecule and the negatively charged atom in another polar molecule. It is weaker than covalent bonds.

How are convalent bonds different from hydrogen bonds

Covalent bonds occur between atoms in one molecule they are intramolecular meaning they are within the same molecule. they are strong bonds because they involve the sharing of valence electrons.

Hydrogen bonds occur between molecules. They are in intermolecular, which means they are between molecules and H bond is a weak attract attractive, force, more similar to an ionic bond due to attraction of opposite charges.

why is water cohesive

Water molecules are attracted to one another because of hydrogen bonding

What is surface tension

Detention of the surface of a liquid water has high surface tensions because of cohesion

What is adhesion

waters attraction to polar or charged objects

Capillary action

Flow of water through a narrow tube without the help of external factors

The water moves through the tube through adhesion and cohesion

What happens when water freezes

The water molecule spread out more than when in liquid form, making ice less dense than water

Solvent

Solute

Solution

Which one is water considered

Solvent is a liquid that dissolves solids and a solute is a solid that dissolves in a liquid a solution is a liquid with a minor component dissolved in the main component

Water is considered a universal solvent because it can dissolve more substances than any other liquid because polar molecules and ionic compounds will dissolve in water

What is specific heat

The amount of heat needed to rise the temperature of 1 g of a substance by 1°C

Water has high specific heat

What is heat vaporization

The amount of heat needed to change 1 g of a liquid substance into a gas

A lot of energy is near the brake hydrogen bonds Meaning that it is very high for water
