Got, it. Just needed to convert iron specific heat from J/(g*K) to J/(kg*K), so delta T is just .549

finally figured it out using the formula: W = PV\gamma(Vf1-\gamma - Vi1-\gamma)/(1 - \gamma)

Homework Statement Two cars collide head on while each is traveling at 80 km/hr. Suppose all their kinetic energy is transformed into the thermal energy of the wrecks. What is the temperature increase of each car? (Assume each car's specific heat is that of iron) Homework Equations K =...

Homework Statement One cylinder in the diesel engine of a truck has an initial volume of 500 cm^3. Air is admitted to the cylinder at 30 C and a pressure of 1.0 atm. The piston rod then does 450 J of work to rapidly compress the air. What is its final temperature? What is its final volume...

Can anyone help me? I am really stuck...

Oh yeah, I see what your saying. However 549 is still the wrong answer, so i must be doing something else wrong too.
