Density, Magnetism, and Conductivity

Front

What is density?

Back

Density is the mass of an object divided by its volume. It tells us how much matter is packed into a certain space.

Front

What is a conductor?

Back

A conductor is a material that allows energy, such as electricity or heat, to flow through it easily.

Front

What is an insulator?

Back

An insulator is a material that does NOT allow energy to flow through it easily.

Front

What does it mean if an object floats in water?

Back

If an object floats in water, it is less dense than the water.

Front

What does it mean if an object sinks in water?

Back

If an object sinks in water, it is more dense than the water.

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, like iron, and is caused by the motion of electric charges.

Front

What is the best example of a conductor?

Back

A metal bowl is a good example of a conductor.

Front

Which liquid is the least dense?

Back

Oil is the least dense among oil, water, syrup, and a plastic bottle.

Front

What happens to the density of an object if you increase its volume but keep its mass the same?

Back

The density decreases because density is mass divided by volume.

Front

What is the principle of buoyancy?

Back

The principle of buoyancy states that an object will float if it displaces a volume of water equal to its weight.
