Leanna is investigating heat transfer using a metal nail and foam cup filled with hot water. First, she records the temperature of the water and nail. Next, she places the nail in the hot water for ten minutes. Finally, she removes the nail from the water and records the temperature of the water and nail. The table shows her data. How does the motion of the molecules in the nail change after the nail is placed in the hot water?

The motion of the molecules in the nail will change after the nail is placed in the hot water. To determine how the motion changes, we need to understand the process of heat transfer.
There are two main mechanisms of heat transfer: conduction and convection. Conduction occurs when heat is transferred through direct contact between two objects. Convection, on the other hand, involves the movement of a fluid (such as water) and the transfer of heat through that fluid.
In this case, the nail is placed in the hot water, which is a fluid. As a result, heat will be transferred from the hot water to the nail. The molecules in the nail will gain energy from this heat transfer and begin to move faster. Therefore, the correct response is: Energy was transferred from the hot water to the nail through convection, causing the molecules in the nail to move faster.
