A helium balloon has a volume of 3.22 L at 21.4C and a pressure of 755mm Hg.

a.) If the balloon is immersed in a cold temperature bath of -63.7C and the pressure remains constant, what will be the new volume in liters of the balloon?

b.) If the same balloon is placed in a vacuum chamber and the pressure is reduced to .551 atm, what will the new volume of the balloon in liters, assuming the temperature remains constant?
