Part II. CALCULATIONAL. Show all work. 1. A. A weather balloon has a volume of 250 ml when filled with helium gas at a temperature of 8 °C and a pressure of 760 mm Hg. The helium balloon floats up into the upper atmosphere (about 20,000 feet above sea- level) where the pressure and temperature are much lower. What is the new volume of the balloon when the pressure is reduced to 570 mm Hg and the temperature decreases to...
