@Since cork floats on water, which one of these statements is correct?
Density of cork is less than the density of water
Density of cork is greater than the density of water
The densities of cork and water must be exactly equal
@Petrol has a density of 0.80 g/cm³. What would be the volume of 1kg of petrol?
1250 cm³

@Why does ice float on water?
Density of ice is less than density of water
Ice is transparent
Ice traps air bubbles which makes it float

Its greater than the density of water
Its less than the density of water
Its less than the density of the surrounding air
