Ahigh-altitude balloon is filled with 1.41 x 104 l of hydrogen at a temperature of 21 °c and a pressure of 745 torr. what is the volume of the balloon at a height of 20 km, where the temperature is -48 °c and the pressure is 63.1 torr

1.27 x 10⁵ L

Explanation:

V₁ = initial volume = 14100 L

V₂ = final volume = ?

P₁ = initial pressure = 745 torr

P₂ = final pressure = 63.1 torr

T₁ = initial temperature = 21 °C = 21 + 273 = 294 K

T₂ = final temperature = - 48 °C = - 48 + 273 = 225 K

Using the equation

= 1.27 x 10⁵ L

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
