A3. A 3 m sealed balloon contains 7 kg of air. The temperature of air is then increased from 25 °C to 45 °C. Given that gas constant of air (R) = 287 J/kgK. Determine a) the volume of the balloon after heating, assuming the pressure in the balloon remains constant; and b) the work (in kJ) of the balloon in expansion.
