state of matter

6. A measure of the amount of solute dissolved in a given quantity of solvent or solution. It is usually expressed in moles per liter (mol/L) or grams per liter (g/L).
8. The temperature at which a solid turns into a liquid. At this temperature, the solid and liquid phases of a substance exist in equilibrium.
9. A term used to describe a substance that easily evaporates at room temperature due to having a low boiling point.
10. A group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

1. Describes two or more liquids that can mix together in any proportion without separating into two phases. For example, alcohol and water are miscible.
2. The process by which a gas turns into a liquid when it is cooled or when it comes into contact with a cooler surface.
3. A substance, typically a liquid, in which a solute is dissolved to form a solution. Water is a common example of a solvent.
4. The smallest unit of an element that retains the chemical properties of that element. It consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.
5. The process by which particles spread from an area of higher concentration to an area of lower concentration, resulting in an even distribution of particles throughout the available
7. A regular, repeating arrangement of atoms, ions, or molecules in a crystalline solid. In a lattice, the particles are arranged in a structured, three-dimensional pattern.
8. A combination of two or more substances in which each substance retains its own chemical identity and properties. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).
11. The process by which molecules at the surface of a liquid gain enough energy to enter the gaseous phase. This can occur at any temperature below the boiling point.
