It depends on the properties of the substance.
At room temperature are most metals solids liquids or gases.
Most of the metals are solids under ordinary conditions i e 25ºc 1 atmosphere of pressure etc with the exception of mercury hg element 80 which solidifies.
The state a given substance exhibits is also a physical property.
They can also be found as solids but they are brittle and nonconductive.
Some substances exist as gases at room temperature oxygen and carbon dioxide while others like water and mercury metal exist as liquids.
On the other hand increasing temperature and decreasing pressure allows particles to move father apart.
Solid liquid or gas.
Matter typically exists in one of three states.
Most metals exist as solids at room temperature.
Substances that conduct an electric current only under certain conditions are most likely to be.
Most non metals are usually liquids or gases at room temperature although not specifically one or the other.
In the periodic table above black squares indicate elements which are solids at room temperature about 22ºc those in blue squares are liquids at room temperature and those in red squares are gases at room temperature.
Depending on the conditions a substance may skip a phase so a solid may become a gas or a gas may become a solid without experiencing the liquid phase.
