The document discusses several physical properties that can be used to identify substances: Density is the mass per unit volume and can be calculated using the formula density=mass/volume. Melting and boiling points refer to the phases of matter - solid, liquid, gas - and the energy absorbed or released during phase changes. Specific heat is the amount of heat needed to raise the temperature of a substance and can be measured in joules per gram per degree Celsius. Solubility measures how much of a substance dissolves in another substance, such as sugar dissolving in water to form a solution.

3. Density Is the mass per unit volume of a material!

4. The formula for calculating density is Density=mass

5. volume

9. The unit of specific heat is joules per gram per degree Celsius.

10. Specific heat values can be used to compare how different substances absorb heat.

12. Solubility is a measure of how much of a substance dissolves in a given amount of another substance.

13. Sugar is soluble(or able to dissolve) in water.

14. When sugar dissolves in water, the two materials form a solution. A solution is a mixture in which the particles are too small to be distinguished from each other.

16. Matter also has chemical properties.

17. A chemical property is a characteristic that describes how the matter will change under certain conditions. One chemical property of matter is reactivity.

18. Reactivity describes how likely an element is to form bonds with other elements.
