Silicon has a relatively large latent heat of vaporization of 12800 J/g. This indicates that silicon has:
beks73 [17]
I believe it means that it takes a lot of heat in joules to make silicon vaporize so it stays solid until a great deal of heat has been added. By comparison, water has a latent heat of about 2260 joules per gram so vaporizes much more readily than silicon.

Compound A melts at 801o C and is soluble
Karo-lina-s [1.5K]

Explanation:

Organic compounds are defined as the compounds which contain carbon as their main element. For example, CH_{3}OH is an organic compound.

Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.

As compound A melts at 801^{o}C and is soluble  in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.

Whereas compound B melts at 24^{o}C and is insoluble  in water. This means that this compound has covalent bonding and it is also non-polar in nature . Hence, it is more likely to be organic in nature.

Thus, we can conclude that compound B is more likely to be an organic

compound.
