Pure Substances And Mixtures Quiz

Matter is the correct answer because it refers to anything that occupies space and has mass. It includes all physical substances, such as solids, liquids, and gases, as well as the particles that make up those substances. Matter is the fundamental building block of everything in the universe, from living organisms to inanimate objects. Water, mixture, and solution are all types or forms of matter, but matter itself encompasses a broader range of substances and materials.

To separate salt from sand and water, you have to boil the solution to evapourate the water.

A solution is a homogeneous mixture composed of two main components: a solvent and a solute. The solvent is the substance that dissolves the solute, creating a uniform mixture. It is usually present in greater quantity and determines the physical state of the solution. The solute, on the other hand, is the substance being dissolved by the solvent. It is typically present in smaller quantities. Therefore, the correct answer is "solvent and solute."

Increasing the temperature, adds energy to the particles, so that they move around faster. This means, the solvent and solute particles will mix together faster.

A homogeneous mixture is a mixture where the components are evenly distributed throughout, resulting in a uniform composition. In a solution, one substance (the solute) is dissolved in another substance (the solvent) to form a homogeneous mixture. Therefore, solution is another name for a homogeneous mixture.

A smaller solute particle dissolves faster than a larger particle (remember the sugar cube and the powdered sugar?)

An atom is the fundamental unit of matter. It consists of a nucleus, which contains protons and neutrons, and electrons that orbit around the nucleus. Atoms combine to form elements, which are substances made up of only one type of atom. Molecules, on the other hand, are formed when two or more atoms bond together. A mixture, on the other hand, is a combination of different substances that are not chemically bonded. Therefore, the correct answer is atom because it is the basic building block of matter.

If the hot chocolate is very weak, it means that there is a large amount of liquid (such as milk or water) compared to the amount of chocolate. This results in a diluted hot chocolate, where the taste and strength of the chocolate flavor is reduced.

Distilled water is a pure substance. It consists of only water molecules, with no other substances or impurities present. It is chemically uniform and has a constant composition throughout.

Particles for solids, liquids and gases can all move. There are spaces between ALL particles.
