This item float on the surface of water.
Dense water sinks in comparison to less dense water.
it becomes less dense
no
Ice is less dense than water
Floating (on water) happens when the item place in the water is less dense than the water. The density of the rock called "pumice" is less than that of water so pumice floats. Pumice is a volcanic rock made form a lava "foam" it is solidified rock froth and therefore is very light.
Gas is much less dense than liquid.
A wooden block can be less dense than water.
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
If more dense, it will sink when put into water; if less dense it floats.
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Oil IS already less dense than water.
Easy, put a fruit in water and if it floats it is less dense than water.
