Initially, a sealed balloon filled with helium gas at 20.0 °C occupies 2.91 L at 1.00 atm. The balloon is then immersed in liquid nitrogen at −196 °C, raising the pressure to 5.20 atm. What is the volume (in L) of the balloon in the liquid nitrogen? Group of answer choices 3.98 L 0.000669 L 5.48 L 0.147 L 2.13 L
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 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?
5. Would you expect the volume of gas contained in a balloon to increase or decrease if it is exposed to lower temperatures? A balloon containing 3.50 L of gas at room temperature, 20 °C, is submerged into a vat of liquid nitrogen. The temperature of liquid nitrogen is 77 K. What will be the volume of the balloon at this very cold temperature? 6. A sample of CO2 gas occupies a volume of 225 mL at 25°C. If the...
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.
1. A helium-filled weather balloon has a volume of 558 L at 22.9°C and 751 mmHg. It is released and rises to an altitude of 3.13 km, where the pressure is 582 mmHg and the temperature is 1.9°C. The volume of the balloon at this altitude is ____L. 2. A sample of helium gas collected at a pressure of 1.42 atm and a temperature of 17.0 °C is found to occupy a volume of 22.9 liters. How many moles of...
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 has a volume of 5.20 L and a pressure of 1248 mmHg when it is inflated on a cool 56 degree F morning. It is ties to a mailbox in the sun, and the balloon heats up to a temperature of 95 degree F and the pressure increases to 2.00 atm. What is the new volume of the balloon?
22. Helium will effuse from a balloon how much faster than nitrogen gas? 23. If 4.0 g of helium gas occupies a volume of 22.4 L at 0°C and a pressure of 1.0 atm, what volume does 3.0 g of He occupy under the same conditions?
