Pure substance: A pure substance is any solid, liquid, or gas that only contains one type of
particles throughout. A pure substance has a definite composition. Examples of pure substances include salt or water. A pure substance can be either an element ( as found on the periodic Table) or a compound.
Mechanical mixture: A mechanical mixture is a mixture where the composition is not uniform.
Solution: A solution is a uniform mixture of two or more pure substances. Unlike mechanical mixtures, solutions are a uniform combination of two or more substances. This means that you cannot see the separate components in the mixture. Solutions are also referred to as homogeneous mixtures. The prefix “homo” means “same”
Matter: Matter is anything that has mass (weight) and takes up space. All the things you have seen, tasted, and touched are made of matter. This is because matter is anything that has mass and takes up space. All matter must have mass.
Chemistry: Chemistry is the study of matter and changes in matter.
Mass: Mass is a measurement that refers to the amount of matter that makes up an object.
Volume: Volume refers to the amount of three-dimensional space that an object or substance occupies.
Solute: Solute is a substance that is dissolved in a liquid (the solvent) to form a solution
Solvent: Solvent is a substance, usually a liquid, that dissolves another substance called a salute, creating a solution.
Saturated: Saturated refers to a state where a system can’t absorb or hold anymore of a substance.
Unsaturated: Unsaturated refers to a compound or solution that is not at its saturation point, meaning it can still absorb or dissolve more of a substance.
Universal Solvent: A universal solvent is a substance that can dissolve a wide range of other substances or chemicals.
Evaporation: Evaporation is the process where a liquid transforms into a gas, typically due to heat, but it can also occur at cooler temperatures.
Sifting: Sifting is the process of separating solid particles based on size using a screen or sieve
Filtration: Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles.
Distillation: Distillation is a separation technique used to purify liquids or separate components of a liquid mixture by selectively vaporizing and then condensing a liquid.
Magnetism: Magnetism used to separate things that are attracted to magnets from other things.
