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.

Carlos Cochran · Answer 1

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

Explanation:

Energy always flows from a hotter object to a cooler one, so the hotplate will cool down and the air will cool down.

The temperature is a measure of the average kinetic energy of the particles, so the atoms in the metal will slow down and the molecules in the air will speed up.
