Does every material have a solid, liquid, and gas state?

At least every element has (apart from many others) a solid, liquid, and gas state. [Although for some this might be very difficult to observe, e.g. Helium is liquid even at T=0 for normal pressure, one needs at least 100atm]

As concerns "meterials": Probably there are many molecules which become unstable before you reach one of those states ...
