To test a balloon, it is placed in a lab and filled with helium. The temperature of the helium is 24 deg C and the pressure is 1.00 atmosphere. The pressure in the lab is maintained. Assume the membrane of the balloon is impermeable to helium. What will happen to the volume of the balloon if the temperature of the helium is increased to 30 deg C while keeping the pressure constant?
1) The volume of the balloon will decrease
2) The volume of the balloon will increase
3) The volume of the balloon will remain the same
4) Cannot be determined
