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 ball does not change significantly, determine the following: a. The amount of heat transferred from the air to the ball during the process.b. The initial pressure to which the balloon must be inflated so that it is at the required measured pressure of 90kPa when it reaches a temperature of 0°C.
