2. A car's tire has a pressure, temperature of 32 psi and 80 deg F, respectively. By mistake, the tire was filled with 0.768 Ib of carbon dioxide (R = 0.0451 BTU/lb-R) before deflating and inflating the tire again with air. Prove that: a. 0.502 Ib of air was needed to fill the tire; and b. that there was change of pressure of 6.442 psi when the car started moving and the temperature increased by 75 deg C.

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.
