At t = 0, a 5 cm thick plate of pure terpium is put into a furnace at 1000 °c with a carbon atmosphere that creates a surface concentration of 2 wt % at both the front and back surfaces. the diffusion coefficient for carbon in terpium at this temperature is 2.5 x 10-9 m2/s. assume that diffusion only occurs into the thickness of the plate but from both directions. (hint: it may to sketch the system). a. on the template below, sketch the c concentration profile in the material at t = 0. (3 pts) b. add values to the vertical axis. (2 pts) c. add a qualitative sketch of the c concentration profile after a short time, t1. (4 pts) d. add a qualitative sketch of the c concentration profile at a later time t2 (3 pts)

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
