The graph below shows the temperature changes occurring in two hot packs that are made from different materials. The same amounts of water and CaCl2 were used to make each pack. Which of the following inferences is supported by the graph? A. Latex is a better conductor than LDPE.
B. During a 60-minute time period, LDPE will release less energy to its surroundings than latex.
C. LDPE would be the best choice for a hand warmer designed to release heat quickly.
D. The LDPE pack reaches its maximum temperature sooner than the latex pack.

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.
