(a) A bar of gold is in thermal contact with a bar of silver of the same length and area . The compound bar is well lagged with one end maintained at 80 degreeC while the opposite end is maintained at 30 degreeC . When the energy transfer reaches a steady state , what is the temperature of the junction ?

(b) The temperature of a silver bar rises by 10 degreeC when it absorbs 1.23 kJ of heat energy. If the mass of the bar is 525 g find the specific heat capacity of silver .
