### Physical Properties of Matter.ppt.pptx

1. 1. Physical Properties of Matter
2. 2. What are properties? ● Matter has observable (using your senses) and measurable qualities that can help us identify, describe, and classify matter. ● Physical properties are the characteristics of matter that can be observed without changing the substance to something else. ● Two basic types of properties of matter: Physical properties and Chemical properties:
3. 3. Examples of Physical Properties: ● Density ● Freezing Point ● Boiling Point ● Melting Point ● Conductivity ● Magnetism ● Solubility ● Ductility ● Malleability These properties don’t change no matter how much you have of a substance. They’re independent!
4. 4. Density A physical property that relates the mass and volume of an object or material. D = M / V Density = Mass/Volume
5. 5. Freezing point ● The temperature at which a liquid changes into a solid. ● Different substances have different freezing points.
6. 6. Boiling Point ● The temperature at which the liquid form of an element or compound turns to a gas. ● The boiling point of water is 100 degrees Celsius, regardless of the amount. ● Different substances have different boiling points.
7. 7. Melting Point ● The temperature at which the solid form of the element or compound becomes a liquid ● The melting point of water is 0 degrees Celsius ● Different substances have different melting points.
8. 8. Conductivity Metals that can transmit heat and electricity easily.
9. 9. Magnetism ● Metals that are attracted to magnets and can be made into magnets.
10. 10. Solubility ● The property of a substance to dissolve in a solvent to form a solution. ● Solute: A substance that dissolves in another substance. ● Solvent: the substance that dissolves the solute. ● Solution: A mixture of 2 or more substances that can not be easily separated and makes a new substance. Example Sugar and Water
11. 11. Ductility ● The property of a substance that allows it to be stretched into a thin wire
12. 12. Malleability ● The property of a substance that allows it to be shaped into a thin sheet
