Question

A helium-filled weather balloon has a volume of 567 L at 20.9°C and 758 mmHg. It is released and rises to an altitude of 8.24 km, where the pressure is 306 mmHg and the temperature is –32.1°C. The volume of the balloon at this altitude is L.

Answer #1

A gas-filled weather balloon has a volume of 60.0 L at ground
level, where the pressure is 763 mmHg and the temperature is 20.9
°C. After being released, the balloon rises to an altitude where
the temperature is –7.29 °C and the pressure is 0.0638 atm. What is
the weather balloon\'s volume at the higher altitude?

A helium weather balloon is filled in Monterey,
California, on a day when the atmospheric pressure is 101,000 Pa
and the temperature is 38°C. Its volume under these conditions is
1.7 E 4 L. Upon being released, it rises to an altitude where the
temperature is -12°C, and its volume increases to 5.7 E 4
L.
A. Assuming that the internal pressure of the balloon equals the
atmospheric pressure, what is the pressure at this altitude?
B. In 1958, a...

A weather balloon is inflated to a volume of 27.4 L at a
pressure of 739 mmHg and a temperature of 30.2 ∘C . The balloon
rises in the atmosphere to an altitude where the pressure is 370.
mmHg and the temperature is -13.4 ∘C .
Assuming the balloon can freely expand, calculate the volume of
the balloon at this altitude (in L).

A weather balloon filled with helium is launched at sea level in
California on a clear day when the temperature is 34 °C and the
atmospheric pressure is 758 torr (recall 760 torr = 1 atm). Before
launch, the balloon has a volume of 100.0 L. What is the mass of
helium, in grams, when the balloon is filled?

a. A very flexible helium-filled balloon is released from the
ground into the air at 20. ∘C. The initial volume of the balloon is
5.00 L, and the pressure is 760. mmHg. The balloon ascends to an
altitude of 20 km, where the pressure is 76.0 mmHg and the
temperature is −50. ∘C. What is the new volume, V2, of the
balloon in liters, assuming it doesn't break or leak?
b. Consider 4.20
L of a gas at 365 mmHg...

A large weather balloon is filled with 1500 moles of helium at
35.0 degrees C and 1.076 atm. What is its final volume at altitude
where the pressure of the atmosphere is 25.0 Torr and the final
temperature is -350 degrees F?

A. A very flexible helium-filled balloon is released from the
ground into the air at 20. ∘C. The initial volume of the balloon is
5.00 L, and the pressure is 760. mmHg. The balloon ascends to an
altitude of 20 km, where the pressure is 76.0 mmHg and the
temperature is −50. ∘C. What is the new volume, V2, of the balloon
in liters, assuming it doesn't break or leak? Express your answer
with the appropriate units.
B. Consider 4.40...

A helium weather balloon is released from ground level where the
temperature is 20⁰ C. The balloon rises to a maximum height of 8.0
miles above the ground. At this height, the balloon expands to a
volume that is 20 times greater than at the release point, and the
pressure of the helium gas is 25 times smaller than at the release
point. What is the final temperature, in ⁰F, of the gas at the
maximum height of the balloon?

A balloon filled with hydrogen gas had a volume of 25000 L at a
pressure of 760 mmHg and a temperature of 0 ∘C. When the balloon
reached an altitude of 1000 m, the pressure was 628 mmHg and the
temperature was − 9 ∘C. What was the volume in liters of the
balloon at these conditions, if the amount of gas does not
change?
A gas sample has a temperature of 23 ∘C with an unknown volume.
The same...
