Benzene has a melting point of 5.5°C and a boiling point of 80.1°C. Given the other constants below for
benzene (C6H6), which of the following processes would require LEAST amount of energy? Assume in
each case the mass of benzene is used.

Csolid = 118.4) · mol-1. K-1
Cliquid = 134.8) · mol-1.K-1
Cvapor = 82.444) .mol-1. K-1
AHvap = 30.77 kJ . mol-
AHfus = 9.9 kJ .mol-1
a) Warming benzene from -10°C to 0°C.
b) Melting benzene from 5.5°C.
c) Warming benzene from 91°C to 101°C.
d) Warming benzene from 65°C to 75°C.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
