5.5A Classifying Matter: Physical Properties

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What are physical properties of matter?

Back

Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as color, shape, size, and density.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What happens to objects with greater density in water?

Back

Objects with greater density than water will sink, while those with lesser density will float.

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to pass through it easily.

Front

Why is metal a good conductor of heat?

Back

Metal is a good conductor of heat because its atoms are closely packed, allowing energy to transfer quickly.

Front

What is the role of a magnet?

Back

A magnet attracts certain metals, such as iron, nickel, and cobalt, due to its magnetic field.

Front

What is an example of a non-magnetic material?

Back

An example of a non-magnetic material is aluminum.

Front

What happens when aluminum is placed in a microwave?

Back

Aluminum can cause sparks in a microwave because it is a conductor of electrical energy.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, determined by the object's density compared to the fluid's density.
