As the pressure of an enclosed gas decreases to half its original value, what happens to the volume of the gas if temperature is held constant? A. The volume decreases to one-fourth of its original value.
B. The volume increases to four times its original value.
C. The volume decreases to half of its original value.
D. The volume increases to twice its original value.

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.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
