1. Question 2 (30 minutes): A cubic block of iron, with 2 cm dimension is subjected to a compression using a 50 ton mass load press. Determine the temperature change of the iron bloc if compression is reversible adiabatic. Take initial temperature of the iron 298 K and constant molar volume 7 cm3/mol. Data: Cp = 24 l/molk a = 1.5 x 10-5 K-1 B = 6 x 10-7 atm-1 = 7.87 g/cm3 at.wt. of Fe = 55,85
