A spherical 8-m-diameter balloon is filled with air under a pressure of 700 kN/m2 abs and at a temperature of 40◦C. Use the ideal gas law equation given by Equation 1.117. (a) Determine the number of moles and the weight of the air in the balloon. (b) Graphically illustrate the effect of the diameter of the balloon on the weight of the air in the balloon by increasing the diameter to 10 m, then to 12 m, for a pressure of 800 kN/m2 abs and 900 kN/ m2 abs, respectivel
