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.

Why do ice cubes float in water?

Back

Ice cubes float because they are less dense than water.

Front

What happens to objects that are denser than water?

Back

Objects that are denser than water sink.

Front

What is the tool used to measure the volume of liquids?

Back

The graduated cylinder is used to measure the volume of liquids.

Front

How can you determine if an object will float?

Back

An object will float if it is less dense than the liquid it is placed in.

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 an object has a mass of 10 grams and a volume of 2 cm³, what is its density?

Back

Density = 10 grams / 2 cm³ = 5 grams/cm³.

Front

What does it mean if a liquid is more dense than another liquid?

Back

It means that the liquid has more mass in the same volume compared to the other liquid.

Front

Can a solid object float in a liquid?

Back

Yes, if the solid object is less dense than the liquid, it will float.
