QUESTION 4 A 0.973 mole sample of helium gas at 25 C filled a balloon to...
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...
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
4. A balloon filled with helium has a volume of 1.28x103 L at sea level where the pressure is 0.998 atm and the temperature is 31°C. The balloon is taken to the top of a mountain where the pressure is 0.753 atm and the temperature is - 25°C. What is the volume of the balloon at the top of the mountain?
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 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 is filled with helium gas. For the question(s) that follow, select the letter of the balloon diagram that corresponds to the given change in conditions. The temperature is changed from 50 °C to -150 °C at constant pressure. A balloon is filled with helium gas.

An arctic weather balloon is filled with 21.2 L of helium gas inside a prep shed. the temperature inside the shed is 5° C. The balloon is then taken outide, where the temperature is -20°C. calculate the new volume of the balloon. O GASES Using Charles's Law an arctic weather balloon is filled with 21.2 L of helium gas inside a prep shed. The temperature inside the shed is 5. °C. The balloon is then taken outside, where the temperature...
Question 23 6 pts A different balloon filled with helium, originally had a volume of 7.50 liters, at 18.0°C. As the day became warmer the new temperature was 38.0°C. What would the new volume of the balloon be, assuming there is no change in pressure or moles of gas? (Show all your work!!!!) Question 23 6 pts A different balloon filled with helium, originally had a volume of 7.50 liters, at 18.0°C. As the day became warmer the new temperature...
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.
