A weather balloon containing helium is released into the atmosphere. As it rises atmospheric pressure and temperature both decreases. Explain why the size of the balloon increases.

What do YOU think.
While we happy to help we will NOT do all the work for you.

Here is your answer. PV=mRT... where p is pressure, V is the volume of the balloon, m is the mass of gas in the balloon (constant) and R is universal gas constant divided by mean molar wt of air (about 28 g/mol) and T is thermodynamic temperature (T in Kelvin; T=273 +t (in deg C). Think pressure.
