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)

Consider a balloon that has a volume V. It contains n moles of gas, it has an internal pressure of P, and its temperature is T. If the balloon is heated to a temperature of 15.5T while it is placed under a high pressure of 15.5P, how does the volume of the balloon change? It doubles. It stays the same. It increases greatly. It decreases slightly.

A balloon has a volume of 219.5 mL. The temperature and pressure of the gas inside the balloon is 333 K and 0.959 atm, respectively. To what temperature (in Celsius) must the balloon be cooled to reduce its volume to 0.19 L if the pressure doesnt change (remained constant)?

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.

The ideal gas law states that PV = NkgT where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant ko is called the Boltzmann constant and has the value kg = 1.38x10-23J/K. A very common expression of the ideal gas law uses the number of moles, n- N/NA (NA is Avogadro's number, NA=6.021023 per mole). PV...
