properties of water vocab- orange

adhesion

the attraction between different types of molecules. It occurs when molecules of one substance interact with molecules of another substance- PROPERTY OF WATER

calorie

a unit of measurement for energy, specifically the amount of heat required to raise the temperature of one gram of water by one degree celsius

capillary action

the ability of a liquid to flow in narrow spaces against gravity due to the intermolecular forces of adhesion and cohesion

cohesion

the attraction between molecules of the same substance, which helps them stick together- PROPERTY OF WATER

covalent bond

a chemical bond formed by the sharing of electron pairs between two atoms

dehydration synthesis

a chemical reaction where two molecules are joined together with the removal of a water molecule

evaporation

the process where liquid water turns into water vapor due to the addition of heat energy

heat of fusion

the amount of energy required to change a substance from a solid to a liquid at its melting point

heat of vaporization

the amount of energy required to convert a liquid to a gas at its boiling point

hydrogen bond

a weak to moderate attractive force between a hydrogen atom covalently bonded to a more electronegative atom and another electronegative atom

hydrolysis

a chemical reaction in which water breaks bonds between molecules, splitting them into small units

hydroxide ion(OH⁻)

a negatively charged ion made up of one oxygen atom and one hydrogen atom

monomer

a small molecule that can bond with other similar molecules to form a polymer

polar covalent bond

a type of chemical bond where electrons are shared unequally between two atoms, creating a molecule with partial positive and negative charges

polarity

the distribution of electrical charges over the atoms joined by a bond. polar molecules have regions of partial positive and negative charges

polymer

a large molecule composed of repeating subunits called monomers

solute

a substance that is dissolved in a solvent to form a solution

specific heat capacity

the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius

sphere of hydration

a shell of water molecules surrounding an ion or polar molecule when it is dissolved in water

surface tension

the cohesive force at the surface of a liquid that makes it behave like an elastic sheet
