Physical Science

Chemical properties are characteristics of a substance that can only be observed when it undergoes a chemical change, resulting in the formation of a new substance.

A chemical change is a process where substances combine or break apart to form new substances, such as baking a cake.

Particles move slowest in a solid state.

A mixture is a combination of two or more substances that can be easily separated.

Rusting is an example of a chemical change.

Physical properties are characteristics of a substance that can be observed without changing its chemical identity, such as color, shape, and boiling point.

A mixture is a combination of substances that can be separated, while a solution is a homogeneous mixture where one substance is dissolved in another.

During a physical change, the form of a substance changes, but its chemical identity remains the same.

An example of a physical change is melting ice into water.

Matter is anything that has mass and takes up space.
