One end of a brass bar is maintained at 305 oC, while the other end is kept at a constant, but lower, temperature. The cross-sectional area of the bar is 2.97 x 10-4 m2. Because of insulation, there is negligible heat loss through the sides of the bar. Heat flows through the bar, however, at a rate of 4.96 J/s. What is the temperature of the bar at a point 0.129 m from the hot end?
What is the piston height if the temperature is 30C. How far apart are the plates if there's air between them.
