Compounds A and B have the same mass, but compound B has two more atoms in its structure. Which statements must be true?

Question

Quizplus · Accepted Answer

The specific heat capacity (Cv) and specific heat at constant pressure (Cp) are intensive properties, which means they do not depend on the amount of the substance. Therefore, since compounds A and B have the same mass, their Cv and Cp values should be independent of the number of atoms in their structures.

Option A and B are incorrect because Cv should be the same for both compounds.

Option C and D are also incorrect because Cp should be the same for both compounds.

Therefore, the only conclusion we can make is that neither Cv nor Cp depends on the number of atoms in the structure of the compounds. This means that the properties of the compounds cannot be compared based on the number of atoms in their structures, so we cannot conclude anything about the relative values of Cv and Cp for compounds A and B.

However, we can conclude that compound B has a more complex structure than compound A because it has two more atoms. Therefore, compound B may have a higher melting or boiling point, a different reactivity, or other different properties compared to compound A. But we cannot infer anything about Cv or Cp based on this information.
