The constant volume Molar heat capacity of ethane, C2H6(g) is 44.3 J/mol-K. When 9.0 kJ of heat is removed at constant volume from 90 grams of ethane, the final temperature is 53oC. What was the approximate initial temperature of the C2H6 before the heat is removed. The correct answer is +120oC. Please show work and explain

A block of iron ore A of mass m = 350 kg and specific heat capacity C = 460 kJ/(kg·K) obeys the constitutive relations where T is temperature. The block of metal is initially at temperature T1 = 700 K and it is placed in a perfectly-sealed, constant-pressure container B containing 64 kg of air initially at 320 K and atmospheric pressure 101.3 kPa. The air in container B can be modeled as a perfect gas with specific heat capacity...
