Why Does Oil Float On Water?

Keithchat1 ton of oil is the same weight as 1 ton of water there will be a difference in size of the container same as with the "whats heavier joke" 1 ton of feathers or 1 ton of lead neither the weight is the same 8)To answer the question as Shifty37 stated:"Water is of greater density that oil. Water molecules are closer together than that of oil, therefore oil floats. Water density is 1000 kg/m while oil is usually about 800 kg/m."

Water is of greater density that oil. Water molecules are closer together than that of oil, therefore oil floats. Water density is 1000 kg/m while oil is usually about 800 kg/m.

Oil has more loosed molecules than water
Also water has greater molecular attraction than oil.

Oil floats on water because oil has less density than water and the the liquid with less density will float on top.

Because its particles aren't as close together weighing it down

Specific gravity people..look it up.

How can 1 ton of oil be heavier than 1 ton of water?
 
But the other guys right, it is because water is denser than oil.
