The investigation designs that explain the heat transfer when atoms directly touch have been the hand touching the handle of the pan sitting on the lit bunsen burner. Thus, option D is correct.
Heat has been the energy that can neither be created nor destroyed. The heat energy can be transferred from one body to another with the transfer of atomic energy.
The atoms of an object gaining energy start to vibrate and transfer the energy to another atom that is in close proximity to the vibrating atoms.
The boiling of water in a pan by sitting it onto the bunsen burner has been an example of the transfer of heat energy. The heat energy of the burner has been transferred to the atoms of the pan that resulting in the boiling of the water in the pan. It has been the transfer of energy in an object.
By touching the pan, the energy of the pan has been transferred to the body. Thus the transfer of energy takes place between two different objects.
Thus, the example of heat transfer between two different objects has been the transfer of energy from the bunsen burner to the pan, and from touching the pan by hands, the energy has been transferred to the hands, Thus, option D is correct.
