Fire is burning gases; sometimes glowing particles are suspended in the flame (usually yellow-orange instead of blue), as in a candle flame. The gases have to be something that will burn, for example methane, carbon monoxide, hydrogen, hydrocarbon waxes, etc., and oxygen must be present. Because these are gases, you cannot liquify or solidy the flame.
