In the next experiment, scientists plan to take the same metal cube, but add 4000J of energy to heat it up from room temperature (23oC) the thermal equilibrium of the water and cube is 25 C. The metal that the cube is made of has a melting point of 450oC and a boiling point of 1280oC. What state of matter will the cube be once it is heated up? Use math to support your 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.
