The ends of a meter stick are maintained at 100ºC and 0ºC. One end of a rod is maintained at 25ºC. Where should its other end be touched on the meter stick so that there is no heat current in the rod in steady state?
Text Solution
Verified by ExpertsThe correct answer is:
C
25 cm from cold end is at 25°C (since temperature gradient is 1°C/cm)
∴ rod should be touched at this point to ensure no heat transfer
