Question

Which element is present in all the three states of matter ?​

Answer 1

Answer:

Water is the only substance where all three states can be readily observed in everyday life: solid water as ice, liquid water in a water fountain, and gaseous water as steam. Carbon dioxide is a good example of a substance which can be a liquid, but only when it is under pressure.

Answer 2

Answer:

in fact all of the elements except for helium go through all three phases of matter (solid, liquid, and gas) as the temperature is varied. That is to say, at low enough temperatures, all the elements (except Helium) are solids. As the temperature is increased they will melt and become liquids.
