This seems like it should be really basic, so it's annoying me that I can't figure it out.
One cylinder in the diesel engine of a truck has an initial volume of 600 cm^3. Air is admitted to the cylinder at 30 degrees celsius and a pressure of 1.0 atm. The piston rod then does 400 J of work to rapidly compress the air. What are its final temperature and volume?
The answers are 1100 K and 23.9 cm^3
In an isobaric process, W = -p delta V
In an isobaric process, V_1 over T_1 = V_2 over T_2
W = -p delta V
400 J = - (600 cm^3 - V_final)
?
Thanks for any help.
