put it in water see if it sinks
If more dense, it will sink when put into water; if less dense it floats.
Put it in water. If it floats, it's less dense. If it sinks, it's more dense.
Gauge its buoyancy. Put it in the water. objects that are less dense will float while objects that are more dense sink.
If it less dense
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.
If its less it floats on the surface of the liquid. If its more it will sink to the bottom.
see if it floats, if it floats it is less dense.
You can either:try the displacement method with a fluid which is less dense than water, ormeasure the volume of a very dense object (which will sink), attach this object to the given solid and find their combined volume. The difference between the two volumes is the required answer.
An object float in a liquid only when the density of the solid is lower than the density of the liquid.
Gauge its buoyancy. Put it in the water. objects that are less dense will float while objects that are more dense sink.
