Because the density of oil is less than the density of water 
So, oil float on water

Bec.the density of oil is less than the density of water so the oil float

because it the oil's density is lower than the density of water so, it floates on the water surface

Because the dinsity of oil is less than the dinsity of the water

Because the oil has less dinisty

because the density of oil is lower than the density of water so it floats on the water surface

because the density less than

because the density of oil is lower than the density of water so it floats on the water surface

Because the density of oil is less than the density of water  So, oil float on water

because it has lower density than the water

because oil smaller than water in dinsty

because the density of oil is lower than the density of water so it floats on the water surface

because the density of oil is lower than the density of water so it floats on the water surface

because the density of oil is lower than the density of water so it floats on the water surface

because the density of oil is less than that of water so it floats on the water's surface

dinisty of oil less than dinesty of water

Because the density of water is less than that of oil

because the oil density less than water

bec   .   the denesty of oil is less then water



 

I think because the oil doesn't dissolve in water.

because the density of oil is smaller than the density of water

because oil is lighter than water

Bec. the denisty of oil is less than the dinesty of water so it float

the density of water is oess than the density of water

because the destiny of oil less than destiny of water

because oil float denstiy is smaller than density of water

Because the density of oil is less than the density of water
