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 helium-filled balloon at 305.0 K and 1 atm, contains 0.35 g He, and has a volume of 1.31 L. It is placed in a freezer (T = 240.0 K), and its volume decreases to 0.90 L. Find ΔE for the gas (in joules). (Cp of He = 20.8 J/mol K.)
A balloon filled with helium gas at 1.00 atm occupies 9.3 L. What volume in liters will the balloon occupy in the upper atmosphere, at a pressure of 0.46 atm?
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)
A balloon filled with helium gad at 1.00 atm occupies 15.5 L. What volume would the balloon occupy in the upper atmosphere, at a pressure of 0.25 atm and a constant temperature?
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?
Question 4 of 21 A sample of an ideal gas at 1.00 atm and a volume of 1.76 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 75.0 atm, what was the volume of the sample? Assume that the temperature was held constant.Questions of 21 A hot air balloon is filled with 1.31 x 10 L of an ideal...
A helium-containing balloon has a volume of 10.6 L and a pressure of 1.22 atm at a temperature of 27.9C. What will the pressure inside the balloon be if the temperature is lowered to -11.3C? Assume that the gas behaves ideally. Express your answer in units of atmospheres (atm) using at least three significant figures.

A helium balloon has a volume of 6.9 L at 28.5 °C and 1.00 atm pressure. The balloon rises to an altitude where the air pressure is 0.76 atm and the temperature is -21.0 °C. What is its volume when it reaches equilibrium at this altitude? (Note: Neglect tension forces in the material of the balloon.)
