A firearm can be modeled as a kind of heat engine, where the projectile acts as a piston that separates from the rest of the system during expansion. Consider a pistol with a mass of 1.60 kg made entirely of iron [specific heat = 448 J/(kg C)]. The pistol fires a 4.00 g bullet that exits the barrel with a speed of 315 m/s. When the propellant is ignited, 1.10% of the energy released goes into propelling the bullet (this is the thermal efficiency of the "engine"). The other 98.9% can be approximated as being entirely absorbed by the body of the pistol, which increases in temperature uniformly for a short time before this energy is dissipated into the surroundings. What is this temperature increase (in C)? (Round your answer to at least one decimal place.) C
