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.

Explanation:

Step1: Understand heat transfer

Heat flows from hot to cold.

Step2: Analyze molecule speed

Faster - moving molecules are in hotter substances. The hot metal plate at 150°C is hotter than the room - temperature air. Heat will transfer from the metal plate to the surrounding air. As heat leaves the metal, the metal molecules slow down. As heat enters the air, the air molecules speed up.

Answer:

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