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 $\mathit{c}{\mathit{m}}^3$. 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 ____ .
