Physical Properties of Science

Front

What is a conductor of thermal energy?

Back

A material that allows heat to pass through it easily. Examples include metals like copper and aluminum.

Front

Which material is the best conductor of thermal energy?

Back

Metal is the best conductor of thermal energy.

Front

What is density?

Back

Density is the mass of a substance divided by its volume. It determines how heavy a substance is for a given space.

Front

Where do the most dense substances typically reside in a container?

Back

The most dense substances are usually found at the bottom of a container.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if it is less dense than the fluid.

Front

What is a non-magnetic material?

Back

A material that does not attract magnets. Example: Aluminum.

Front

What is a magnetic material?

Back

A material that can be attracted by a magnet. Examples include iron, nickel, and cobalt.

Front

What happens to the density of a substance when it is heated?

Back

Generally, the density decreases as the substance expands when heated.

Front

What is the principle of buoyancy?

Back

An object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
