Study Notes
Physical Properties and Changes
- A Physical Property is observable or measurable without altering the substance's identity.
- Key Physical Properties include color, shape, texture, luster, mass, weight, volume, density, state, flexibility, magnetism, conductivity, malleability, ductility, and solubility.
Specific Physical Properties
- Flexibility refers to the ability of a material to be stretched or bent.
- Magnetism involves the capability to attract metallic objects.
- Conductivity is the measure of a substance's ability to transmit electricity.
- Malleability describes a material's ability to be deformed under compression, such as being hammered into shape.
- Ductility is the ability of a substance to be stretched into wires without breaking.
- Solubility is the capacity of a substance to dissolve in water.
Chemical Properties and Changes
- A Chemical Property indicates how a substance can change to form new substances through a reaction.
- Common Chemical Properties include rust formation, flammability, and reactivity.
Specific Chemical Properties
- Rust occurs when iron reacts with oxygen, resulting in a new compound.
- Flammability signifies a material’s ability to catch fire and burn.
- Reactivity is the ability of two substances to interact and form new chemical products.
Types of Changes
- Physical Change: An alteration where the substance's appearance changes without transforming into a different substance.
- Chemical Change: A transformation resulting in the formation of one or more new substances with different properties.
Examples of Changes
- Souring of milk is classified as a Chemical Change.
- Shredding cheese exemplifies a Physical Change.
- Iron rusting represents a Chemical Change.
- Wood burning is also a Chemical Change.
- Crushing bread is an example of a Physical Change.
- Eating food involves both types of change: Physical Change during chewing and Chemical Change during digestion.
