Density

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

Which liquid is the least dense?

Back

Oil is the least dense liquid compared to water, syrup, and a plastic bottle.

Front

What tool is used to measure the volume of a liquid?

Back

A graduated cylinder is used to measure the volume of a liquid.

Front

How can you tell which liquid is the most dense when they do not mix?

Back

The most dense liquid will be at the bottom.

Front

What happens to an object that is less dense than the liquid it is in?

Back

An object that is less dense than the liquid will float.

Front

Why does a brick sink in water while a wooden block floats?

Back

A brick sinks because it has a higher density than the wooden block.

Front

What is the relationship between density and buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which depends on the object's density compared to the fluid's density.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

If two objects have the same volume, but one is heavier, which one is denser?

Back

The heavier object is denser.

Front

What happens to the density of a substance if you increase its volume while keeping its mass the same?

Back

If you increase the volume while keeping the mass the same, the density decreases.
