Answer:
Solid
Explanation:
From the question above we have that a heat of 4000J of energy is needed for the experiment. Also, the metal that in consideration has a melting point of 450°C and a boiling point of 1280°C.
We also have that the experiment Is going to start at the temperature of the room which equals to 23°C.
A pure water boils between the ranges of 98°C - 100°C and it needs about 2257kJ per 1 gram of water to boil. Therefore, if 4000J of heat is needed and the boiling point of the metal is 1280°C, the metal cube will still be at the same state, that is a solid.
