Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

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.
Measuring the drop in pressure with a manometer as a function of temperature within a sealed container filled with an ideal gas provides a technique to show that the magnitude of "zero absolute temperature" or OK corresponds to -273 °C. If this experiment is conducted, starting at 1 atm and 67 °C, instead of in boiling water, what will the pressure be, in mmHg, when cooled to 0°C?
