Physical properties like density, melting and boiling points, and specific heat can be used to identify substances. Density is a substance's mass per unit volume. Melting point is the temperature when a solid turns to a liquid, while boiling point is when a liquid turns to a gas. Specific heat is the amount of heat needed to raise the temperature of a substance. Solubility measures how well a substance dissolves in another, and chemical properties describe how a substance changes under certain conditions like reactivity.

1. Identifying Chemicals Kelly and Kristina

2. A physical property is a way to identify a substance using mass, volume, color, hardness and density.

4. The formula for density is d=m/v.

6. The Melting Point of water is 0 degrees Celsius.

7. Boiling Point is where the temperature of gas bubbles form in a liquid and rise to the surface and escape a liquid to a gas.

9. Different Specific Heats are used to compare how different substances absorb heat.

11. An example of solubility is sugar dissolving in water.

12. Sugar dissolves into water it forms a solution, which is a mixture when the particles are too small to be distinguished from each other and remain constantly and uniformly mixed.
