2. A helium balloon with a volume of 1.25L is purchased at a county fair (assume 25°C and 1 atm pressure). The balloon is accidentally released and floats away. It ascends into the upper atmosphere, where the pressure is a lot lower. Before it bursts, the balloon has expanded to a volume of 3.80L. What is the change in entropy as a result of this expansion (ignore any temperature change in the upper atmosphere)? (5 points)
