2. A four-cylinder car engine typically has ~2.3 L total displacement, each one of which holds 0.58

L of fuel + air gas mixture. When the fuel + air gas mixture enters the piston at 1 atm pressure at

a standard engine temperature of -90 °C (again 0.58 L volume), it is compressed adiabatically and

irreversibly by a constant external pressure of 2000 kPa. Assuming Cv,m = 20.8 J/K/mol, what is

Aq, n, Pf, Tf, AU, Aw, and AH? Assume perfect gas behavior.
