A balloon holds 38 kg of helium. What is the volume of the balloon if the pressure is 1.3 atm and the temperature is 24 °C?
NTERACTIVE EXAMPLE General Gas Law Helium-filled balloons are used to carry scientific instruments high into the atmosphere. Suppose a balloon is launched when the temperature is 21.5 °C, and the barometric pressure is 752 mm Hg. If the balloon's volume is 4.37x10L (and no helium escapes from the balloon), what will the volume be at a height of 20 miles, where the pressure is 76.0 mm Hg, and the temperature is -33.0 °C?

Learning Goal: To apply the ideal gas law to problems involving temperature, pressure, volume, and moles of a gas. The four properties of gases (pressure P, volume V, temperature T, and moles of gas n) are related by a single expression known as the ideal gas law: PV=nRT The variable R is known as the universal gas constant and has the value R=0.0821 L⋅atm/(mole⋅K). The units of R dictate the units for all other quantities, so when using this value...
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) How many atoms of helium gas fill a spherical balloon of diameter 30.8 cm at 19.0°C and 1.00 atm? atoms (b) What is the average kinetic energy of the helium atoms? (c) What is the rms speed of the helium atoms? km/s
A helium balloon rises from the ground where the temperature and pressure are 23 °C and 1.0 atm. When the balloon reaches a height of 1 km, the temperature and pressure have both decreased to 13 °C and 0.90 atm. Assuming that the helium behaves as an ideal gas, predict the volume of the balloon at 1 km if its initial volume was 2.1 L. any heplp would be appreciated.
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...
