A cylinder of volume 43.8 L helium is filled to a gauge pressure of 1.72 x 10^7 Pa in a cylinder. a) With that amount of helium, how many balloons can be inflated to a volume of 4.0 L and pressure of 1.01 x 10^5 Pa, assuming that the balloons and the cylinder are at the same temperature? b) If the temperature of the balloons is 77 degrees Fahrenheit, then how many moles of helium are in one balloon? c) If the balloons are spherical, then how many Newtons of force does the helium exert on the interior of one balloon, assuming that the thickness of the balloon is negligible?

Large helium-filled balloons are used to lift scientific equipment to high altitudes. What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0 degree C and rises to an altitude where its volume is twenty times the original volume and its temperature is -48DegreeC ? What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)

1) A cylinder is filled with 0.10 mol of an ideal gas at
standard temperature and pressure, and a 1.4-kg piston seals the
gas in the cylinder (see figure) with a frictionless seal. The
trapped column of gas is 2.1-m high. The piston and cylinder are
surrounded by air, also at standard temperature and pressure. The
piston is released from rest and starts to fall. The motion of the
piston ceases after the oscillations stop with the piston and the...
