yep
Because it is less dense than water. Basically, there is more space between atoms of aluminum than molecules of water, sort of like water and oil.
Aluminium is more dense than PET.
Ice is less dense than water
A wooden block can be less dense than water.
An aluminum nail that is less dense than the element aluminum would not be made of pure aluminum, but would have to be an alloy of aluminum and some other substance. If an aluminum nail is made of pure aluminum, it would have the same density as the "actual" element.
no
Oil IS already less dense than water.
Easy, put a fruit in water and if it floats it is less dense than water.
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Yes. Anything that is less dense than water will float on water.
Have you heard of Archimedes. Well he stated that the weight of water displaced by an object is equal to the weight of the object. From here we conclude that object being more denser than water sinks those being less dense than water floats. An Aluminum cube has a much higher density than that of water and the sheet is less dense than water. Thus the former floats while the latter sinks. Now you also might have noticed that an iron nail sinks while an iron ship floats. I hope now you can answer this question!!
Water is less dense than any of the other materials listed.In order of density from least to highest:Water (least dense)GraniteBasaltIron (most dense)
