Large helium-filled balloons are used to lift scientific equipment to high altitudes.

(a) What is the pressure inside such a balloon (in atm) if it starts out at sea level with a temperature of 20.8°C and rises to an altitude where its volume is twenty-two times the original volume and its temperature is −25.7°C? (Enter your answer to at least 3 decimal places) atm

(b) What is the gauge pressure? (Enter your answer in atm and to at least 3 decimal places. Assume atmospheric pressure is constant.) atm

A balloon, which even weighs 0.934 g, is filled with helium at normal atmospheric pressure (101.3 kPa) at room temperature (20.0 ° C) and is then volume 6.19 dm3. How much does the balloon weigh when filled with helium? ( )g. A balloon that weighs less than the equivalent volume of ambient air will, according to Arkimede's principle, be lifted if it is released, while one that weighs more will fall to the ground. How much would the corresponding air...

Chapter 5- Gases 24. As weather balloons rise from the earth's surface, the pressure of th atmosphere becomes less, tending to cause the volume of the balloons to exand. However, the temperature is much lower in the upper atmosphere that at sea level. Would this temperature effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you? 37. Freon-12 (CF2Cl2) is commonly used as the refrigerant in...
