The liquid state of matter can do this, as its atoms aren’t as tightly connected as the ones in solids. Imagine you have a big pile of marbles. In this analogy, solids would be strong magnetic marbles, which, once formed, would keep their shape. Liquids would be like barely bonded marbles, basically loose, which would accomodate themselves to the bowl where they would be in. And gas would be floating marbles, flying around, spreading whenever empty space can be found.
B. Ionic solids have higher melting points than molecular solids.

Explanation:
Usually, when we write a chemical formula for any compound or other chemical specie, we use subscripts to;
- Indicate the ratio of atoms of each element present in the compound or chemical specie
- Show the number of atoms of each element present in the compound or chemical specie.
Hence, the subscripts written after chemical formulas have more than one function as described above.
In H2SO4 for instance, there are two hydrogen atoms, one sulphur atom and four oxygen atoms as shown in the chemical formula.
