50. What mass of helium, in grams, is required to fill 5.0-L balloon to a pressure of 1.1 atm at 25°C?
A helium balloon has a volume of 6.9 L at 28.5 °C and 1.00 atm pressure. The balloon rises to an altitude where the air pressure is 0.76 atm and the temperature is -21.0 °C. What is its volume when it reaches equilibrium at this altitude? (Note: Neglect tension forces in the material of the balloon.)
1. If a balloon holds 2000 L of helium at sea level, at 1 atm and 25 °C, what will its vol- ume be if it is allowed to rise to a height of 8 miles, where the pressure is 0.30 atm and the temperature is-70°C? 2. What is the mass of 40.0 L of NH3 at 1.50 atm and 45 °C?
A balloon filled with 2.00 L of helium initially at 1.35 atm of pressure rises into the atmosphere. When the surrounding pressure reaches 500. mmHg, the balloon will burst. If 1 atm = 760. mmHg, what volume will the balloon occupy in the instant before it bursts?
A helium-containing balloon has a volume of 10.6 L and a pressure of 1.22 atm at a temperature of 27.9C. What will the pressure inside the balloon be if the temperature is lowered to -11.3C? Assume that the gas behaves ideally. Express your answer in units of atmospheres (atm) using at least three significant figures.
A balloon that contains 0.500 L of helium at 25 °C is cooled to 11 °C, at a constant pressure. What volume does the balloon now occupy?
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.
QUESTION 4 A 0.973 mole sample of helium gas at 25 C filled a balloon to a volume of 3.87 L. What is the pressure of the balloon? 6.15 atm 1.12x103 atm 74.9 atm 0.516 atm
What mass of neon gas is required to fill a 4.37-L container to a pressure of 1.28 atm at 27°C?
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?
