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.
