A balloon is inflated with 0.1247mol of Helium gas to a pressure of 1.26atm. If the volume 1.25L, what must the temperature be in Kelvin?

Explanation:

Let consider that helium behaves ideally. The equation of state of the ideal gas is:

The temperature is cleared in the expression presented above:

The temperature of the helium inside the balloon is:

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.
