Thermodynamics of a Helium Gas Filled Balloon

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

A balloon is filled with helium gas at 20.0ºC at 1.0atm (1atm = 1.01x10^5 N/m^2).The volume of the balloon after filling is measured to be 8.50m^3. The helium is then heated at constant pressure until its temperature is 55.0ºC. What is the heat flow into the gas? (CP for an ideal gas is (5/2)R.)
