In [[planetary science]], '''volatiles''' are that group of [[chemical elements]] and [[
Planetary scientists often class volatiles with exceptionally low melting points, such as [[hydrogen]] and [[helium]], as '''gases''' (as in [[gas giant]]), while those volatiles with melting points above about 100 K are referred to as '''ices'''. The terms "gas" and "ice" in this context can apply to compounds that may be solids, liquids or gases. Thus, [[Jupiter]] and [[Saturn]] are referred to as "gas giants", and [[Uranus]] and [[Neptune]] are referred to as "ice giants", even though the vast majority of the "gas" and "ice" in their interiors is liquid.
