A bar of lead (bar A) is in thermal contact with a bar of copper (bar B) of the same length and area (see the figure below). One end of the compound bar is maintained at Th = 84.0°C, and the opposite end is at 30.0°C. Find the temperature at the junction when the energy flow reaches a steady state.

View Policies Current Attempt in Progress Air is compressed in a piston-cylinder assembly from p₁ = 25 lbf/in², T₁ = 500°R, V₁ = 9 ft³ to a final volume of V₂ = 1 ft3 in a process described by pv¹.25 = constant. Assume ideal gas behavior and neglect kinetic and potential energy effects. Using constant specific heats evaluated at T₁, determine the work and the heat transfer, in Btu.

What is the maximum theoretical efficiency possible for an engine operating between 100°C and 400°C?
