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 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 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.
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...
