Chemical change explained in an easy to understand way.

a property that is not visible until a substance undergoes a chemical reaction, like solubility

Chemical property explained in an easy to understand way.

the process where substances change into different substances through the breaking of chemical bonds

Chemical reaction explained in an easy to understand way.

the substance made when atoms from two or more elements combine chemically

Compound explained in an easy to understand way.

The separation of substances in a liquid mixture by evaporating it and condensing the vapor

Distillation

The separation of substances in a liquid mixture by evaporating it and condensing the vapor. Distillation. Distillation is a process used to purify or separate liquids by heating them to create vapor and then cooling the vapor back into a liquid.

a substance made of one type of atom that cannot be broken down chemically

Element explained in an easy to understand way.

Energy explained in an easy to understand way.

A property that depends on the amount of matter in a sample. e.g. mass, length

Extensive property

A property that depends on the amount of matter in a sample. e.g. mass, length. extensive property. An extensive property changes when the size or amount of the sample changes.

The process of passing a liquid or gas through a filter to remove waste

Filtration

The process of passing a liquid or gas through a filter to remove waste. Filtration. Filtration is a method where unwanted particles are removed from a liquid or gas by using a filter.

a state of matter that has no fixed shape or volume

Gas explained in an easy to understand way.

A mixture in which substances are not evenly mixed

Heterogeneous mixture

A mixture in which substances are not evenly mixed. Heterogeneous mixture. In science, a heterogeneous mixture is one where you can see the different components, like a salad with various ingredients not blended together.

A mixture in which substances are evenly mixed (also called a solution)

Homogeneous mixture

A mixture in which substances are evenly mixed also called a solution. Homogeneous mixture. A homogeneous mixture is when different components are combined so well that they appear as a single substance.

A property independent of the amount of matter in a sample. e.g. density, temperature

Intensive property

A property independent of the amount of matter in a sample. e.g. density, temperature. intensive property. Intensive properties do not change with the size of the sample, like how boiling point remains constant regardless of how much liquid you have.

States that mass cannot be created or destroyed in a chemical reaction

Law of conservation of mass

States that mass cannot be created or destroyed in a chemical reaction. Law of conservation of mass. It means that in a chemical reaction, the total mass of the substances involved stays the same.

The elements of a compound are always present in the same proportions by mass

Law of definite proportion

The elements of a compound are always present in the same proportions by mass. Law of definite proportion. This law means that no matter how much of a compound you have, the ratio of its elements by weight is constant and unchanging.

When two elements combine to form different compounds, the mass of one element combines with the same mass of the other element in a ratio of small whole numbers

Law of multiple proportion

When two elements combine to form different compounds, the mass of one element combines with the same mass of the other element in a ratio of small whole numbers. Law of multiple proportion. This law states that elements can combine in different ways to form different compounds, but the ratios of the masses of these compounds will be simple whole numbers.

a state of matter that has definite volume but no definite shape

Liquid explained in an easy to understand way.

a combination of substances that keep their individual properties

Mixture explained in an easy to understand way.

Molecule explained in an easy to understand way.

a chart of all the elements, arranged by their physical and chemical properties

Periodic table explained in an easy to understand way.

a change in size, shape, or state but not in identity

Physical change explained in an easy to understand way.

a property of a substance we can observe without changing its identity, like color or hardness

Physical property explained in an easy to understand way.

a new substance formed by a chemical reaction

Product explained in an easy to understand way.

An element or compound that consists of only one type of particle. e.g. oxygen, honey

Pure substance

An element or compound that consists of only one type of particle. e.g. oxygen, honey. pure substance. A pure substance is a material with a uniform and definite composition.

a substance that is changed in a chemical reaction

Reactant explained in an easy to understand way.

the state of matter with definite shape and volume

Solid explained in an easy to understand way.

a mixture of evenly distributed substances

Solution explained in an easy to understand way.

The three forms of matter - solid, liquid, and gas

States of matter

The three forms of matter - solid, liquid, and gas. States of matter. States of matter refer to the different forms in which matter can exist, based on the arrangement and movement of its particles.

Water vapor explained in an easy to understand way.
