see if it floats, if it floats it is less dense.
You can determine whether a solid substance is more or less dense than water by comparing their densities. If the density of the substance is greater than the density of water (1 g/cm^3), then the substance is more dense. If the density of the substance is less than the density of water, then the substance 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.

The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
Rub the substance on a paper bag, if it leaves a grease stain, it is a Lipid.
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.
the melting point
no !
Typically pressure and temperature determine whether a substance is gas, liquid or solid. Some substances however are not easily forced into some of the states, and that is determined by by individual molecular qualities.
