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!!!!)

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...
Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...
A helium-filled balloon has a volume of 2.9 L at 23◦C. The volume of the balloon decreases to 2.5 L after it is placed outside on a cold day. What is the outside temperature in ◦C?
A helium-filled balloon has a volume of 2.9 L at 23◦C. The volume of the balloon decreases to 2.5 L after it is placed outside on a cold day. What is the outside temperature in ◦C? Answer in units of ◦C.
A helium-filled balloon has a volume of 2.9 L at 23◦C. The volume of the balloon decreases to 2.5 L after it is placed outside on a cold day. What is the outside temperature in K? Answer in units of K.
A balloon originally has 0.10 moles of helium and has a volume of 0.50 L. If 0.59 grams of He are added to the balloon, what will the new volume be, in L? (Assume temperature and pressure do not change.)
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 weather balloon with a volume of 44L is filled with 2.0 mol of helium. What is the final volume, in liters if 3.0 mol of helium are added, to give a total of 5.0 mol of helium, if the pressure and temperature do not change?
A weather balloon has a volume of 765L when filled with helium at 10°C added pressure of 395 tour what is the new volume of the balloon in liters if the balloon rises to a point where the air pressure is 235 tour and the temperature is -24°C
