The engine of a sports car takes in air at 25°C at 1 atm. It compresses it adiabatically to 0.1 times the original volume. The air may be treated as an ideal gas with g = 1.4.

a) What is the final temperature of the gas in Celius?

b) If the volume of air intake is the equivalent of 1 m3, at this temperature and pressure, how many moles of air does the engine intake?

c) How much energy did it take to warm the air assuming that the air is N2 and Cv = (5/2)R

The volume of air taken in during a typical breath is 0.47 L. The inhaled air is heated to 37∘C (the internal body temperature) as it enters the lungs. Because air is about 80% nitrogen, N2, model it as an ideal gas. Suppose that the outside air is at room temperature (17.0∘C) and that a person takes two breaths every 3.0 s. Assume that the pressure does not change during the process. How many joules of heat Q1does it take...
