This is because the rest are false, as solids are able to melt, and do have melting points. Also, not all solids have the same melting points.
Answer:
Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.
Since nonmetals have five, six, or seven electrons in their valence shells, it takes less energy to gain the necessary electrons, and therefore form anions.
All elements can be classified as metals, metalloids, or nonmetals
