Study Notes
Physical Properties
- Matter is anything that has mass and takes up space
- Physical properties describe matter without changing its identity
- These properties can be size-dependent or size-independent
Size-Dependent Properties
- Mass: a measure of the amount of matter in an object
- Weight: the force of gravity acting on an object's mass
- Volume: the amount of space an object or substance occupies
Size-Independent Properties
- Luster: a gentle sheen or soft glow
- Texture: the feel or consistency of a surface or substance
- Color: the appearance of a substance
- Malleability: the ability to be shaped into something without breaking
- Hardness: the resistance to scratching by another object
- State of matter: solid, liquid, or gas
- Melting and freezing point: temperature at which a substance changes between a solid and a liquid
- Boiling Point: temperature at which a substance changes between a liquid and a gas
- Solubility: the ability of one substance to dissolve into another
- Conductivity: the ability to carry an electric current or thermal energy
- Density: the amount of mass per unit of volume
- Magnetism: the motion of electric charge resulting in attractive and repulsive forces
- Viscosity: a liquid's resistance to flow
Chemical Properties
- Chemical properties describe how matter changes into a different substance
- Flammability: the ability to support burning
- Reaction with oxygen: characteristic of a substance reacting with oxygen
- Reaction with sulfur: characteristic of a substance reacting with sulfur
- Acidity: the amount of hydrogen or hydronium ions present in a solution
Changes in Matter
- Physical Change: a change in form or appearance, but no new substance is formed; it can be reversed
- Chemical Change: a change where one or more new substances are formed, different from the original; it cannot be reversed.
- Indicators of a Chemical Change: color change, gas production (bubbles, foaming, smoke), change in oder, emission of energy (light, heat, or sound)
