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 containing 4.00 moles of N2 gas has a volume of 0.750 L at a pressure of 1.00 atm and a temperature of 27°C. What will the new volume of the balloon be, in liters, if the pressure is doubled to 2.00 atm, the temperature is increased to 127°C, and 1.50 moles of N2 is removed from the balloon? On an airliner, an inflated toy has a volume of 0.310 L at 25°C and 745 mmHg. During flight, the...
How many moles of neon are present in 44.8 L of neon under the conditions of standard temperature and pressure (273.0K; 1.00atm)? In this case, is it convenient to use the gas constant of 0.08206 L atm mol^-1K^-1?
25. You’re at the zoo and have a big red 3.20 L helium balloon. The barometric pressure is 790.0 mm Hg. Then you hear the roar of a lion. Startled, you accidently release the balloon. It flies away.
