Physical Properties. Physical properties do not change the chemical nature of matter. A physical change occurs in shape, form, or appearance but no new substance is created. Examples of physical properties include color, odor, hardness, texture, luster, volume or size, shape, solubility (ability to dissolve), molecular polarity

When a physical change occurs, only the form of the substance changes. Chemical changes, however, result in the formation of new substances with different properties. Some general signs of a chemical change include a change of color or odor, the formation of a precipitate (solid), the formation of a gas, and a change in heat or light.

Salts have unique chemical and physical properties such as electrical conductivity and high melting points. Ionic bonds are relatively strong bonds and therefore require a lot of energy to break resulting in high melting and boiling points. This laboratory will investigate the physical properties of some common household chemicals.

Chemical and physical properties of substances can be used to match a suspect to a crime scene. This is very frequently done with blood samples, but as no one was willing to donate about a quart of blood for this experiment, we will have to use simpler substances. Question: Can you match a suspect to the crime scene?! Materials:
