A soccer referee inflates a soccer ball to the standard required measured pressure for a game of 90kPa, before the game. The balloon has an internal volume of 2650 cm3 and the air is at a temperature of 25°C when the balloon is first inflated. The ball is brought onto the field of play, and by the time the game starts, the air temperature has dropped to 0°C. Assuming that the volume of the balloon does not change significantly. Determine the following: a. Make a schematic of the system, showing the limits and conditions b. The mass (in Kilograms) of air in the ball. c. The air pressure in the ball when the game starts. (Measured pressure)
