A balloon is filled up completely with helium gas and left in a room with a...

A balloon is filled up completely with helium gas and left in a room with a controlled temperature of 230C. After two days of being in the same room, the balloon was found to have shrunk to half its filled-up size. However, there was no leakage of helium gas from the balloon during the two days. Explain what happened to the pressure inside the balloon due to the change in the size of the balloon. ? Use Boyle's Law to explain...

A balloon filled with 39.1 moles of helium gas has a volume of 876 L at...

A balloon filled with 39.1 moles of helium gas has a volume of 876 L at 0.0°C and 1.00 atm pressure. At constant pressure, the temperature of the balloon is increased to 38.0°C causing the balloon to expand. Calculate q, w, ∆E for the helium in the balloon. The specific heat of helium gas is 5.20 J/(g °C) and 101.3 J = 1 Latm.
