Question

If a rod is put in a hot water heat flows from higher temperature to lower temperature after sometime it attains steady state where the heat which goes inside comes outside it without changing the temperature of respective cross sections in the rod therefore it does not melt now and then but when we want to actually melt it what we will do? if it attains steady state every time then we wouldn't be able to melt anything . Give your options like when it will attain steady state and when it will melt and under what conditions

Answer 1

Answer:

The molecules of water moved around faster as they were heated up. ... These faster moving water molecules transfer energy to the metal rod where they are touching. The energy from the hot water makes the molecules of the metal rod move faster, which we can feel as the rod heating up.
