D.) "Vaporization" <span>is not a form of heat transfer.
It is just conversion of the state of matter from Liquid to Vapor
Hope this helps!</span>
WHat's a concept map again?

Answer:
mass = 6.56 grams
Explanation:
No of molecules = No of moles × Avogadro's constant
Similarly, number of moles = mass/ molar mass
∴
mass = 6.56 grams
Completely natural process with almost no harmful side effects
Answer:
CCl4
Explanation:
Let us look at the structure of CCl4 closely in order to really determine if it is the correct answer to the question or not.
While it is true that the electro negativity of carbon is 2.5 and that of chlorine is 3.0, hence an electro negativity difference of 0.5 exists between carbon and chlorine leading to the presence of four polar covalent bonds in the carbon tetrachloride molecule. We must also observe that the molecule, carbon tetrachloride, has a tetrahedral molecular geometry. This implies that the four dipoles in the molecule are symmetrical and cancel out each other hence the molecule is non polar. Being a non polar molecule, only London forces are expected to be present as an intermolecular force, hence the answer.
