A weather balloon filled with helium is launched at sea level in
California on a clear day when the temperature is 34 oC
and the atmospheric pressure is 758 torr (recall 760 torr = 1 atm).
What is the density of the gas in grams/Liter?
A 110.0 L of weather balloon filled with 6.9 moles of helium has
a small leak. If the helium leaks at a rate of 10mmol/hr, what is
the volume of the balloon in 43 hours?
A) A helium-filled weather balloon has a volume of 593 L at
16.9°C and 752 mmHg. It is released and rises to an altitude of
7.34 km, where the pressure is 354 mmHg and the temperature is
–27.1°C. The volume of the balloon at this altitude is L.
B) A sample of helium gas occupies a volume of
7.24 L at 52.0°C and
1.14 atm.
If it is desired to increase the volume of the
gas sample to 9.74 L,...
A 3.0 g latex balloon is filled with 2.8 g of helium. When
filled, the balloon is a 32-cm-diameter sphere. When released, the
balloon accelerates upward until it reaches a terminal speed. What
is this speed? Assume an air density of 1.2 kg/m3 and a drag
coefficient for sphere of 0.47.
A
balloon filled with 6.50 L He rises from sea level to a height
where the pressure is 700 mm Hg. Would the volume of the gas in the
balloon be greater than, equal to, or less than at sea level? Also,
can you explain why?
A spherical balloon has a radius of 6.95m and is filled with helium. The density of helium is 0.179 kg/m3, and the density of air is 1.29 kg/m3. The skin and structure of the balloon has a mass of 960kg. Neglect the buoyant force on the cargo volume itself. Determine the largest mass of cargo the balloon can lift.
An empty rubber balloon has a mass of 0.0105 kg. The balloon is
filled with helium at a density of 0.181 kg/m3. At this density the
balloon is spherical with a radius of 0.300 m. If the filled
balloon is fastened to a vertical line, what is the tension in the
line?
A balloon is filled up completely with helium gas and left in a
room with a controlled temperature of 230C. After two days of being
in the same room, the balloon was found to have shrunk to half its
filled-up size. However, there was no leakage of helium gas from
the balloon during the two days. Explain what happened to the
pressure inside the balloon due to the change in the size of the
balloon. ? Use Boyle's Law to explain...
A helium-filled balloon has a volume of 0.010 m3. The
temperature in the room and in the balloon is 20 C What are the
average speed of a particle of helium inside the balloon? What is
the thermal energy of the helium in the balloon? Assume that due to
stretching of the balloon the pressure inside it is 1.1 atm.
A
spherical balloon has a radius of 7.15 m and is filled with helium.
The density of helium is 0.179 kg/m^3, and the density of air is
1.29 kg/m^3. The skin and structure of the balloon has a mass of
910 kg. Neglect the buoyant force on the cargo volume itself.
Determine the largest mass of cargo the balloon can
lift.
A balloon filled with 2.00 L of helium initially at 1.25 atm of
pressure rises into the atmosphere. When the surrounding pressure
reaches 330. mmHg, the balloon will burst. If 1 atm = 760. mmHg,
what volume will the balloon occupy in the instant before it
bursts?
