A sample of hydrogen gas occupies a volume of 6.38 L at 48.0°C and 0.490 atm. If it is desired to increase the volume of the gas sample to 8.10 L, while increasing its pressure to 0.655 atm, the temperature of the gas sample at the new volume and pressure must be °C.

The final temperature 271.77 °C

Explanation:

Given:

Initial pressure atm

Final pressure atm

Initial temperature 48° C = 321 K

Initial volume L

Final volume L

From ideal gas equation,

      K

      271.77°C

Therefore, the final temperature 271.77 °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.
