Consider one-dimensional heat conduction through a plane wall with no energy generation. The temperature distribution across a wall 0.5 m thick at a certain instant of time is given as T(x) = a + bx, where T is in C and xis in meters, while a = 20C, b= -300C/m. The wall area is 20 m, and it has the properties = 1200 kg/m, k= 25 W/mK, and Cp= 2 kJ/kgK. (3 points)(A)Determine the rate of heat transfer entering the wall (x= 0) and leaving the wall (x= 0.5 m).(B)Determine the rate of change of energy storage in the wall (Est).(C)Determine the time rate of temperature change (dT/dt).
