4. For computer chip of 25 mm (length), 9 mm(width) is operated by power of 0.645 Watt, which surrounded by coolant material of temp of 85 F. Find the Surface Temperature in F of the computer chip during the heat transfer of convection. The Internal energy is 5.5 J/sec, KE-6.9 Usec, and PE-35 watt (Hints: heat convection, Q=-hAdT heat transfer coefficient, h-150W/sq.m K, W-J/sec, Apply 1 law of thermodynamics) 5. A system of known mass (4kg) is located at the height of 1000m to a process for the work (100 kJ) and heat transfer (25 kJ) and the specific internal energy change (25 kJ/kg). Find the Change in Kinetic Energy in kJ (Hint, use 1 Law of thermodynamics).
