A gas is most likely to change the liquid phase in the pressure of the gas

if pressure rises in closed vessel and temperature is low enough,

Gas may condense to liquid state

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
