Give three examples each of (a) natually found composites and (b) man-made composites found in everyday life. (must not be already mentioned in the textbook or class slides) also list what is the matrix and reinforcement in these composites list briefly the relative advantages and disadvantages of metal, ceramic and polymer matrix composites what is the difference between a lamina and a laminate?

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.
