Question

Silicon has a relatively large latent heat of vaporization of 12800 J/g. This indicates that silicon has:

Answer 1

strong attraction between liquid particles

Answer 2

Explanation:

When without any change in temperature heat required for conversion of unit mass of a liquid into its vapor state is known as latent heat of vaporization.

When we say a molecule has large heat of vaporization then it means that the liquid or substance has strong intermolecular forces of attraction between its particles and to overcome those forces high heat needs to be provided.

Whereas low heat of vaporization means the intermolecular forces between particles of a liquid or substance can be overcome by slight or low heating of the substance.

Thus, we can conclude that when silicon has large latent heat of vaporization of 12800 J/g then this indicates that particles of silicon are held by strong intermolecular forces. Therefore, high heat is required to change silicon from liquid to vapor state.
