Air containing gasoline vapor is admitted into the cylinder of an internal combustion engine at 1.00 atm pressure and 30 °C. The piston rapidly compresses the gas from 500 cm3 to 50 cm3, a compression ratio of 10. This type of compression is too rapid for heat to be transferred from the gas to the environment, so it can be modeled as an adiabatic compression. (a) What are the final temperature and pressure of the ? (b) Show the compression process on a pV diagram. (c) How much work is done to compress the gas? [air is a mixture of N2 and O2, diatomic gases, so use yair 1.4 L7. as 0]

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
