see if it floats, if it floats it is less dense.
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.

Rub the substance on a paper bag, if it leaves a grease stain, it is a Lipid.
put them both in a tub of water and if one floats its not as dense as the other if it sinks its more dense
Being solid and dense are "physical" characterists. So, they depend on the INTERmolecular forces betweens the species of the substance(this one is a crystalline so it is composed of ions). Therefore, substance exists as dense solid because the intermolecular forces are strong.
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
If its less it floats on the surface of the liquid. If its more it will sink to the bottom.
Water, as ice.
put it in water see if it sinks
