A helium-filled weather balloon has a volume of 646 L at 22.9°C and 752 mmHg. It is released and rises to an altitude of 3.07 km, where the pressure is 586 mmHg and the temperature is 2.9°C. The volume of the balloon at this altitude is L.
A helium-filled balloon has a volume of 3.50 L in the warm store at 21.1 ∘C . When it is taken outside, where the temperature is 2.50 ∘C , the balloon has shrunk somewhat. By how much has the volume decreased?
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.
A weather balloon is filled with helium to a volume of 350 L at 12 ∘C and 747 mmHg . The balloon ascends to an altitude where the pressure is 499 mmHg and the temperature is -36 ∘C What is the volume of the balloon at this altitude? Express your answer using three significant figures.
A balloon filled with 35.6 moles of helium has a volume of 856 L at 0.0°C and 1.00 atm pressure. The temperature of the balloon is increased to 43.0°C as it expands to a volume of 967 L, the pressure remaining constant. Calculate q, w, and ΔE for the helium in the balloon. (Given, the molar heat capacity for helium gas is 20.8 J/°C · mol, and 1 L·atm = 101.3 J) (Show your work)
Question 23 6 pts A different balloon filled with helium, originally had a volume of 7.50 liters, at 18.0°C. As the day became warmer the new temperature was 38.0°C. What would the new volume of the balloon be, assuming there is no change in pressure or moles of gas? (Show all your work!!!!)
