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.

LAB 7. DETERMINING THE ATOMIC WEIGHT OF MAGNESIUM 2. A gas sample in a balloon contains 4.0 moles of gas at a particular pressure, volume and temperature. If your balloon springs a leak and the volume decreases to 1/2 of the original amount before you can plug the leak, how many moles of gas have you lost (temperature and pressure remain the same)? 3. A sample of O, gas was collected over H,O in a 550 mL container at 21°C...
A flexible balloon contains 0.350 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 6900 cm3 and a temperature of 30.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K and γ=4/3. What is the total heat Q supplied to the gas in the process? What is...
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 balloon contains 0.114 mol of gas and has a volume of 2.51 L . If an additional 0.183 mol of gas is added to the balloon (at the same temperature and pressure), what will its final volume be?
deal gases obey the equation PV nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of gas, T is its temperature, and the constant R-8.314 KPa-liters-mol-1 kelvin-1 (a) Find the exac t change in volume of O, gas as the pressure increases from 12.00 to 12.01 KPa, the temperature decreases from 300.0 to 299.9 degrees kelvin, and the number of moles of 0, gas changes from 1.03 to 1.01 moles....
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)
A Flexible Balloon A flexible balloon contains 0.315 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7400 cm and a temperature of 29.0°C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp = 33.26 J/mol. K and y = 4/3. Part A What is the total heat...
Gas laws 1) A balloon has a volume of L at 20°C and 101.325 kPa pressure. If the pressure stays constant but the temperature increases to 45°C what will the volume of the balloon be? 2) Determine the volume occupied when 40g of O₂ is at 30°C at standard pressure,
A helium-filled balloon at 1.00 atm pressure has a volume of 1.200 L. It is placed in a freezer and its volume decreases, stopping at 1.010 L. (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.) Calculate ΔE for the gas in the balloon.
A helium-filled balloon at 1.00 atm pressure has a volume of 1.320 L. It is placed in a freezer and its volume decreases, stopping at 0.990 L. (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.) Calculate ΔE for the gas in the balloon.
