Yes, the density of a candle is slightly less than water so it will float at cold and hot temperatures; however water density gets lower with increase in temperature; if you get very close to boiling point (100C or 212F) it may sink.
Type your answer here... the oil has more density
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
The density of tar is lower.
Ice floats because it is less dense than water. The lower density is because in ice the molecules are arranged into a hexagonal crystal structure that leaves extra space in between.
It will sink when you put it in water. If it floats it has less density then water.
With out knowing further knowledge about the rock it is unable to determine the exact density. However, since the rock floats, presumably in water, the density must be less then 1.00g/L.
the density of water is higher than the density of wood... & so an iron piece sinks & a ton of wood floats...
when some thing is less dense than the liquid it floats
An object will float in water if it has LESS density than the water.
The density of snow is lower than the density of water.
Oil floats on water, and has a lower density.
If the density is more than 1 (gram per cc), then a solid lump of it sinks in water. Less than 1, it floats.
Water floats when it is in the solid phase, called ice. Ice floats because the density of ice is less than the density of water.
That the material's density is less than the density of water.
everything which has less density than water will float.....
Wood mostly floats in water because it has a lower density than water. it is NOT lighter than water, it is LESS DENSE. water has a density of 1.0 g/cm cubed. that means wood usually has a density of .99 or less. But, not all wood floats, keep that in mind
