Question

When the hot iron block is placed in the beaker containing room temperature water, what happens to the kinetic energy of the water?

Answer 1

The object that is hot will cool down and the water will soon heat up. Eventually both objects will have the same temperature

Answer 2

The kinetic energy of the iron block is transferred to the water. This results in a cooling of the iron block and a heating of the room temperature water. The two will reach an equilibrium then both cool down as the kinetic energy espaces into the atmosphere
