A football was inflated to a gauge pressure of bar when the ambient temperature was 15°C. When the game started next day, the air temperature at the stadium was 5°C. Assume that the volume of the football remains constant at 2500 cm³. The amount of heat lost by the air in the football and the gauge pressure of air in the football at the stadium respectively equal to (a) 30.6 J and 1.94 bar (b) 21.8 J and 0.93 bar (c) 61.1 J and 1.94 bar (d) 43.7 J and 0.93 bar A football was inflated to a gauge pressure of bar when the ambient temperature was 15°C.
