A and B are two huge blocks of same metal. The blocks are connected by a huge rod of the same material. The temperatures of A and B are 1500\text{ K} and 500\text{ K} respectively. The rate of heat conduction is 10^4\text{ J sec}^{-1}. Estimate the rate of entropy increase of the universe due to this process.
