the unit of density is

g cm³

g cm^-3

g cm²

g cm

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

mass X volume

mass - volume

mass / volume

volume / mass

Balloon containing helium gas float in the air because

helium gas denser than air

helium gas less dense than water

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

The density of A is

10 gcm-3

20 gcm-3

5 gcm-3

1 gcm-3

the density of B is 5gcm-3. the volume of B is 30 cm3. the mass of B is

30 g

150 g

35 g

50 g

if the density of B is 1.5 gcm-3, and density of water is 1.0 gcm-3, then

the water will float

B will float on water

B will sink in water

both water and B will sink

oil

water

syrup

plastic bottle

19.

Why do some substances float on water?

they are warmer than water

they are cooler than water

they are more dense than water

they are less dense than water

20.
