Gas/Vapours turn to liquid by contracting due to condensation, but on heating their physical state cannot reverse back into solid or liquid.
Hence, a gas on heating will remain a gas itself as it expands.
Furthermore, answer to your question is all gases like oxygen O2, carbon dioxide CO2, Hydrogen H2, N2O , C4H10 , C3H8,Ar ,He ,N2,etc.
