To test a balloon, it is placed in a lab and filled with helium. The temperature of the helium is 10.0°C and the pressure is 1.00 atmosphere. The pressure in the lab is maintained. Assume the membrane of the balloon provides a negligible inward pressure, so it is not considered significant.

(a) What is the pressure inside the balloon if the helium is replaced with helium that is at - 50.0°C? and the balloon is filled until it has a volume of 20.0 times its original volume?

(b) What is the gauge pressure? (Assume the pressure in the lab remains at 1.00 atmosphere during the experiment.)
