Physical/Chemical Properties Quiz

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.
