Step-by-step explanation:
think about water to find the first 3. this represents any other material. only the temperatures of changing the state is different.
and then about rocket engines or welding for the 4th.
water can be liquid. normal water as coming out of the faucet.
water can be solid (as in frozen) - ice.
water can be a gas : steam (visible), when we boil it, or invisible vapor, when it is standing still and simply evaporating.
and the mentioned very high temperature state : plasma is the 4th.
in this state at least the molecules split into the atoms, and the electrons separate from the atom cores. and sometimes even the atom cores can split into the elementary parts.
FYI
measurements of the inner parts of planets like Jupiter hint towards a 5th state : hydrogen at the core of Jupiter in a liquid/metallic (and therefore also solid) state.
then there is the matter state in a neutron star (squeezed together so that everything is reduced to neutrons).
and last but not least there is matter in a black hole, where we have only some very strange theories (like elastic thin pipes that weave together).
