Question 1

If a substance has a heat of condensation of -1.46 kJ/g and a heat of sublimation of 4.60 kJ/g, what is its heat of solidification in kJ/g?
◦ 4.60 - 1.46 kJ/g
◦ -(4.60 + 1.46) kJ/g
◦ 1.46 - 4.60 kJ/g
◦ 4.60 + 1.46 kJ/g
◦ 0 kJ/g

Question 2

If one compares compound A, composed of nonpolar molecules, with compound B, composed of polar molecules, and both molecules have the same molecular formula, then it is true that:
◦ both compounds have the same boiling point
◦ A boils at a lower temperature than B
◦ B will not boil
◦ B boils at a lower temperature than A
◦ we have to know the structural formula to determine the differences in boiling points of A and B
