The weight of the substances are largely immaterial. What matters is the density. Assuming fresh water to have a density of 1.0 anything with a lighter density will float in it. For example, oil generally has a density of about 0.8, so it floats in water. Concrete has a density of about 2.4, so it sinks. http://physics.about.com/od/fluidmechanics/a/commondens.htm
a green liquid
Soil floats on water!
A pepper floats higher than an apple because of its shape and lighter weight.
the difference between salt water and fresh water is that salt water is from the ocean and fresh water is water that hasn't gotten to the ocean and so the water is clean, And you can only drink fresh water not salt water
Of course. Fresh water floats on salt water, warmer water floats on cooler water, and ice floats on any water.
Salt water is denser than fresh.
salty water is more dense than fresh
fairy moss
freeze water as ice cubes then put it on water and it floats Liquid fresh water floats on salt water Warm water floats on cold water (water's greatest density is when it is 4 degrees Celsius).
sea water is denser.
oil doesn't settle in salt water nor fresh water, it floats to the top
Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.
I think that salty ice cube do float in water because ice bergs float it water and they're made of salty water. i think i depends on the density (Amount of salt) in the ice
Water displacement. :\ less resistance in clean water.
It's not the color that is significant, its the fresh water that the ice cubes were made with. Salt water is heavier than fresh water so the fresh water floats a top the salt water.
Fresh eggs float in salt water because the density of salt water is more than the density of the egg. But fresh eggs do not float in fresh water because the density of water is less than that of the egg. Salt increases the density of water.
