Q. An engine goes by the following cycle with 2.10 sample of a diatomic gas. I. an isothermas expansion from point a to point b. II. a constant pressure compression from point b to point c. III. An adiabatic compression from point c to point a. We are given point a has a temperature 401, and a volume 1.20×10-3.

What is the pressure in Pascals at point a?


What is the pressure in Pascals at point b if the volume of point b is 0.400?


What is the volume at point c?


What is the temperature at point c?


What is the change in internal energy for process II (constant pressure)?
