• Hardness-this is the ability of an object to withstand wear or scratches
• Solubility- the ability of a substance to dissolve in a solvent.
• Solids have a definite shape and volume. They cannot be deformed easily
• Liquid- they take up the shape of their container but still retain their own volume. They can flow and are compressible
• Gas- they do not have any fixed shape or volume, they fill the entire container and expand when heated
• Solid to gas - sublimation
• Gas to Solid- deposition
• Gas to Liquid- Sublimation
• Liquid to Gas- boiling
• Liquid to solid- freezing
• Solid to Liquid- melting
