Can a substance exist in all three states of matter simultaneously?

Answer 1

For substances, the temperature and pressure at which all three states of matter exist in thermodynamic equilibrium is called the triple point. However, a mixture would have two or more different substances with different melting and boiling points, meaning the triple point of each would be different.

Answer 2

Every element has a specific point of pressure and temperature, called the triple point, which allows all three states of matter to exist together in equilibrium.

The same is true for many compounds.

The exceptions that occur are a result of a chemical reaction taking place caused by the change in pressure or temperature. For instance, larger organic compounds can decompose before they reach a temperature where they would vaporize.

A change in state is a physical change, i.e. liquid, gas, solid. It is sometimes possible for a compound to undergo a chemical change which preempts the physical change.

Answer 3

There is no one element that fits this criterium. Every element can exist in 3 states of matter. Water, a molecule, can simultaneously exist as a solid, liquid and gas if that is what you are asking.

Answer 4

Water is not the only substance that can exist in three states. Look at table of elements. Everything has melting point and boiling point. All matter has it's own unique properties. Take Mercury for example it has ability to evaporate at higher temperatures, it is liquid at room temperature and if you cool it down it will crystallize.

Answer 5

Most elements have three states of matter. The exceptions are as follows:Arsenic sublimates at 889 K ( = 616 deg C),

Carbon sublimates at 4098 K ( = 3825 deg C),

Elements 96 onwards are thought to be solid at room temperature (20 deg C = 293 K) but their melting and boiling points are not known.

Finally, at normal atmospheric pressure, helium has a very peculiar behaviour around absolute zero.

Answer 6

No, a substance cannot exist in all three states of matter simultaneously. A substance can only exist in one state of matter at a time, depending on its temperature and pressure conditions.

Answer 7

Yes, at the triple point.

Answer 8

All elements can be obtained as solids, liquids or gases.

Answer 9

All elements can be obtained in three states of matter.

Answer 10

Most elements exist in three (or more) states of matter under suitable conditions.
