What is a chemical reaction?

• A process in which one or more substances (reactants) are transformed into new substances (products) with different properties by breaking bonds, rearranging, and forming new chemical bonds.

• The process by which a gas turns into a liquid.

• The cooling of a liquid below its melting point.

• The distinct physical form in which a substance exists, such as solid, liquid, or gas, which is determined by the arrangement and movement of its particles.

What are compounds?

• Tiny particles that make up everything around us.

• Substances that are formed as a result of a chemical reaction.

• Pure substances made up of only one type of atom.

• Substances formed when two or more different atoms chemically bond together.

What is condensation?

• The process by which a gas turns into a liquid.

• The mass per unit volume of a substance; how tightly packed particles are within a substance.

• The process by which a substance transitions directly from a solid to a gas, or vice versa, without passing through the liquid phase.

• The energy an object has due to its motion, as determined by its velocity and mass.

What is conserved (conservation)?

• The force exerted on a surface divided by the area over which the force is applied.

• Characteristics or qualities that describe matter, such as color, shape, size, and texture.

• This principle states that certain properties, such as mass and energy, remain constant during physical and chemical changes.

• A state of matter characterized by particles that are far apart and move freely, filling the space available to them.
