1.5 Density

The formula of density( g cm^-3) is

• mass X volume

• mass - volume

• mass / volume

• volume / mass

the unit of density is

• g cm³

• g cm^-3

• g cm²

• g cm

petrol density = 0.80 gcm^-3, water density =1.00 gcm^-3

• the water is less dense than petrol

• the water is denser than petrol

ice is float in water because

• ice less dense than water

• ice is denser than water

3 layer tea can be prepare using the concept of

• water displacement method

• density

Ballon gas contain helium gas float in the air because

• helium gas denser than air

• helium gas less dense than water

volume of A is 10 cm³. the mass of A is 100 g.

The density of A is

• 10 g cm^-3

• 1 g cm^-3

• 20 g cm^-3

• 5 g cm^-3

volume of A is 5 cm³. the mass of A is 100 g.

The density of A is

• 10 gcm-3
