A football was inflated to a gauge pressure of bar when the ambient temperature was 15C. When the game started next day, the air temperature at the stadium was 5C. Assume that the volume of the football remains constant at 2500 cm. 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
