Question

A hot metal plate at 150°C has been placed in air at room temperature. Which event would most likely take place over the next few minutes? Molecules in both the metal and the surrounding air will start moving at lower speeds. Molecules in both the metal and the surrounding air will start moving at higher speeds. The air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up. The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

Answer 1

The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

This means the air around will heat up, and the plate will cool down. They are trying to reach a thermal equilibrium.
