Acompound consisting of atoms of large atomic mass is more likely to require:
a. a higher temperature to liquefy
b. a lower temperature to liquefy
c. less kinetic energy to melt
d. more kinetic energy to freeze

Option (a) is the correct answer.

Explanation:

An atom with large atomic mass means it will have more number of electrons and more intermolecular forces of attraction between them. Therefore, in order to liquefy the compound we need to provide kinetic energy to its molecules.

And to provide kinetic energy to more number of electrons we need to heat the compound at high temperature so that intermolecular forces of attraction between large number of atoms can be overcome.

Thus, we can conclude that a compound consisting of atoms of large atomic mass is more likely to require a higher temperature to liquefy.

false

because it does not have the potential to be entirely used up
