# Problem P. 3882. (March 2006)

**P. 3882.** There is a sample of diatomic gas in a container (whose volume is constant). The temperature of this gas was increased greatly so some molecules fell into atoms (dissociated) and the pressure of the gas increased by a factor of 9.2 and the internal energy of the gas increased to a value of 8.24 times the original internal energy. *a*) What percent of the molecules dissociated? *b*) By what factor did the temperature of the gas (measured in Kelvins) increased?
