A 3 m3 sealed balloon contains 7 kg of air. The temperature of
air is then increased from 25 ºC to 45 ºC. Given that gas constant
of air (R) = 287 J/kgK. Determine a) b) the volume of the balloon
after heating, assuming the pressure in the balloon remains
constant; and the work (in kJ) of the balloon in expansion.
