A helium balloon with 2.5L of gas has a gauge pressure of 10,000 Pa. The balloon is heated at a constant pressure until it has a volume of 3L. How much work did the helium do?
A helium balloon with 2.5L of gas has a gauge pressure of 10,000 Pa. The balloon...
Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...
A helium-filled toy balloon has a gauge pressure of 0.250 atm and a volume of 10.0 L. How much greater is the internal energy of the helium in the balloon than it would be at zero gauge pressure?
Atmospheric pressure is 101000 Pa. A toy balloon is inflated with helium at a constant pressure that is 890000 Pa in excess of atmospheric pressure. If the balloon inflates from a volume of 0.00081 m^3 to 0.00101 m^3, how much work is done by the balloon on the surrounding air? Answer in units of J.
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)...
The balloon contains 0.30 mol of helium starts at a pressure of 110 kPa and rises to an altitude where the pressure is 55.0 kPa , maintaining a constant 300 K temperature. A) By what factor does its volume increase? B)How much work does the gas in the balloon do?
a balloon contains gas at a pressure 1.2 atm (1 atm=101.3kpa) and has a volume of 0.10m^3. more gas is pumped into the balloon at a constant pressure until the volume is doubled. how much work is done by the pump? A) 12 J B) 24 KJ C) 24 J D)12 KJ E) 6.1 KJ
1. A helium-filled weather balloon has a volume of 558 L at 22.9°C and 751 mmHg. It is released and rises to an altitude of 3.13 km, where the pressure is 582 mmHg and the temperature is 1.9°C. The volume of the balloon at this altitude is ____L. 2. A sample of helium gas collected at a pressure of 1.42 atm and a temperature of 17.0 °C is found to occupy a volume of 22.9 liters. How many moles of...
A balloon contains 1 moles of helium gas at normal atmospheric pressure (Patm = 1.01 105 Pa) and room temperature (293 K). The volume of the balloon is 0.024 m^3. (b) The weather becomes very stormy (a hurricane is approaching), and the volume of the balloon increases by 10.9%. What is the new pressure? ______kPa? (the answer is not 9.26x10^2)
