What is the basic definition of density?

• The weight of an object in air.

• The mass of an object per unit volume.

• The volume of an object per unit mass.

• The amount of space an object occupies.

How is density calculated?

• By dividing mass by volume.

• By multiplying mass and volume.

• By subtracting volume from mass.

• By adding mass and volume.

Which of the following is an example of density in real life?

• The height of a building.

• The buoyancy of a ship.

• The color of a flower.

• The speed of a car.

What happens to the density of an object if its mass increases but its volume remains the same?

• The density increases.

• The density remains the same.

• The density becomes zero.

• The density decreases.

Why is understanding density important in material science?

• It is crucial for understanding material strength and buoyancy.

• It helps in measuring the temperature of materials.

• It helps in determining the color of materials.

• It is used to calculate the age of materials.
