| physical property | feature of matter that can be observed or measured without changing the chemical makeup of a substance |
| volume | amount of space an object takes up |
| mass | amount of matter in an object |
| weight | measure of the force, or pull, on objects due to gravity |
| malleable | able to be hammered into thin sheets |
| brittle | easily breakable |
| ductile | able to be drawn out into a wire without breaking |
| conductivity | ability of a material to convey or conduct heat and electricity |
| magnetic | ability to attract a magnet |
| hardness | ability to resist being scratched |
| density | measurement of the mass per unit volume of a substance |
| physical change | change in an object’s appearance, but not in its composition |
| mixture | two or more substances that are mixed together but are not chemically joined |
| sublimation | changing directly from a solid to a gas |
| homogeneous | made of two or more substances that mix together evenly |
| dissolve | to spread evenly throughout another substance |
| solution | homogeneous mixture in which particles of one substance are spread evenly throughout the other substance |
| solute | substance that dissolves in a solvent to form a solution |
| solvent | substance in which a solute dissolves to form a solution |
| solubility | how much solute will dissolve in a certain amount of solvent at a certain temperature |
| concentration | amount of solute in a solution compared with the amount of solvent |
| unsaturated solution | solution that can dissolve more solute |
