1.1 Find the resistance of 1000m of a copper wire with a cross sectional area of 25 mm2. The resistance of copper is 1/58 ohm per metre length and 1 mm2 cross-
sectional area. What will be the resistance of another wire of the same material, three
times as long and one-half area of cross section?

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.
