One end of a rod is held in a fire, while the other is held by one’s hand. Just assume his hand doesn’t get burned. After some time the rod-hand system is in thermal equilibrium. True or False?

Correct Answer: False
In the given situation, after some time a steady state will be reached. That is temperature at individual points will be constant, but there will be a difference of temperature between 2 points along the length of the rod. For, this heat flow will be continuous so we can’t call it thermal equilibrium.
