1. Water Quizs

Polar

• A molecule that has one end pulling electrons (negative) closer, creating a more negative side and a more positive side

• A molecule that has equal sharing of electrons, resulting in no charge separation

• A molecule that is completely neutral with no charge distribution

• A molecule that repels water and does not mix with it

Hydrogen bond

• A strong bond between two molecules resulting from the sharing of electrons.

• A weak bond between two molecules resulting from an electrostatic attraction (a more positive area will be more attracted to a more negative area)

• A bond formed by the complete transfer of electrons from one atom to another.

• A bond that occurs between two nonpolar molecules due to temporary dipoles.

Nonpolar

• A molecule in which the electrons are shared equally between the nuclei.

• A molecule that has a positive and a negative end.

• A molecule that is soluble in water.

• A molecule that has a high electronegativity difference between atoms.

Covalent bond

• A type of chemical bond where two atoms share a pair of electrons.

• A bond formed by the transfer of electrons from one atom to another.

• A weak attraction between a hydrogen atom and an electronegative atom.

• A bond that occurs between metal and non-metal atoms.

Buoyancy

• The ability to sink in water

• The ability to float in water or air

• The weight of an object in water

• The force exerted by a solid object

Hydrophobic

• Tending to repel or fail to mix with water. Often nonpolar molecules.

• Attracting water molecules and mixing well with them.

• Having a strong affinity for polar molecules.

• Being soluble in water and forming hydrogen bonds.

Hydrophilic

• Having a tendency to repel water.

• Having a tendency to mix with, dissolve in, or be wetted by water.

• Being resistant to moisture.

• Having a neutral reaction to water.

Cohesion

• The action or property of like molecules sticking together. Water sticking to water.

• The action or property of unlike molecules sticking together. Oil and water.

• The process of water evaporating into the atmosphere.

• The ability of water to dissolve other substances.

Adhesion

• The action or process of adhering to a surface or object.

• The ability to repel water from a surface.

• The process of breaking down substances into smaller parts.

• The phenomenon of mixing two different liquids.

Solute

• A substance that can be dissolved in water, such as salt or sugar.

• A type of chemical reaction that occurs in water.

• A solid that cannot dissolve in any liquid.

• A gas that forms bubbles in liquids.
