Question:

The gases that closely resemble air after combustion in an automobile cylinder are expanded such that the volume increases by a factor of 8. If the initial pressure is 275 psia, estimate the final temperature and the work produced if the initial temperature is
a) 800° F,
b) 1100° F,
c) 1400° F. Assume constant specific heats from Table B-2E. Assume a frictionless process.
