Consider lead, in what state will it be at each of the following temperatures?
a) 4000 degrees Celsius, b) 40 degrees Celsius, c) 400 degrees Celsius, d) 327 degrees Celsius.
Look up the melting point of Pb and the boiling point of Pb.
Then T < melting point it is solid.
T = m.p. equilibrium between liquid and solid.
T > m.p. but < b.p. is liquid
T > b.p. is vapor
