Quick Notes

Physical properties are the properties that can be identified by using our five senses or measuring tools

Chemical properties are the properties of a substance that become evident when it changes to a new substance.

• The ability of a material to float or sink in water.
• A material that has a lower density will float
• A material that has a higher density will sink.

• Melting point is the temperature at which a substance changes from solid to liquid.
• Boiling point is the temperature at which a substance changes from liquid to gas
• Melting point water: \(0^\circ{\text{C}}\)
• Boiling point water: \(100^\circ{\text{C}}\)

• Ability of a substance to dissolve in given amount of solvent to form a solution.
• The solubility of a substance depends on the physical and chemical properties of its solute and solvent
