Write an MC68000 assembly language program that will add four word sized numbers located in an array starting at absolute address $1000. Do not destroy these original values or any part of them. Choose small values so that there is no carryout or overflow. The sum should still be restricted to word sized for simplicity. The result should be placed at the memory location specified in register A5. The program should be written in the form of a loop, not as individual statements for addition.

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.
