The specific heat capacity of air is given by = 1040 /.. Three moles of air is initially at 340K. If 7,000 Joules of energy is added to the air. We can do an energy balance, by stating that all the energy is added to the thermal internal energy of the air = _T0^T_f 1.Calculate mass of the air, then do the integral to calculate the final temperature. 2. Suppose the specific heat capacity is temperature dependent, = (1040 + 0.0004) /. Use this expression to calculate the final temperature.
