If moles and pressure are constant, what is the volume of decane gas at 7°c if 23 ml of decane gas has a temperature of 43k

According to Charles' law for ideal gases, at constant pressure, the volume of a given mass and moles of gas is directly proportional to its temperature in the Kelvin scale.

Therefore,

Here,

V1 = Initial volume of decane gas = 23 mL

T1 = Initial temperature of decane gas = 7 degree C = ( 7 + 273.15) K = 280.15 K.

T2 = Final temperature of decane gas = 43 K

V2 = Final volume of decane gas = ?

The required volume of decane gas is 149.8 mL.

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.
