Q:
Part A: A nonexpandable balloon is filled with He gas to a pressure of 107kPa when the temperature is 22 degrees Centigrade. If the temperature is increased to 45 degrees Centigrade, what will be the pressure of the He gas in the balloon. I solved this part (its 115kPa) but part B says:
B) If a regular rubber balloon were used, what would the pressure be at 45 degrees centigrade?
This problem has two non constant variables. I have no clue how to solve it or set up the equations.
