A football was inflated to a gauge pressure of 1 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. Gauge pressure of air to which the ball must have been originally inflated so that it would equal 1 bar gauge at the stadium is (a) 2.23 bar (c) 1.07 bar (b) 1.94 bar (d) 1 bar A football was inflated to a gauge pressure of 1 bar when the ambient temperature was 15°C.
