0A football was inflated to a gauge pressure of 1 bar when the ambient temperature was 15 C c . When the game started next day, the air temperature at the stadium was 5C 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:
(A) 30.6 J, 1.94 bar
(B) 21.8 J, 0.93 bar
(C) 61.1 J, 1.94 bar
(D) 43.7 J, 0.93 bar
