Helium inside a balloon was initially at 4.4 atm when filled to 5.0 × 10 2 L then the pressure was reduced to 1.1 atm at a constant temperature. We’re being asked to determine the volume of the gas after decreasing the pressure.
Recall that the ideal gas law is:
The pressure and volume of a gas are related to the number of moles, gas constant and temperature. The value nRT is constant.
If the pressure in a helium-filled balloon is 4.4 atm when filled to 5.0 × 10 2 L, what volume is occupied by the helium-filled balloon when the pressure is reduced to 1.1 atm?
(a) 2.0 × 102 L
(b) 2.5 × 102 L
(c) 2.2 × 102 L
(d) 2.0 × 103 L
(e) 3.0 × 102 L
