Asealed balloon is filled with 1.00 l of helium at 19°c and 1.09 atm. the balloon rises to a point in the atmosphere where the pressure is 222 torr and the temperature is −28 °c. what is the change in the volume of the balloon as it ascends from 1.09 atm to a pressure of 222 torr?

change in volume of ballon is  2.109 L

Explanation:

Given data:

initial temperature = 199 degree C = 292 K

pressure P1 = 1.09 atm

initial volume = 1.00 L

pressure P2 = 222 torr = 0.292 atm

temperature T2 = - 28 oC = 245 K

we know that

V2 = 3.109 L

change in volume of ballon = 3.109 - 1 = 2.109 L

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
