Question

Hot metal plate at 150°C has been placed in air at room temperature. Which event would most likely take place

ver 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

When a hot metal plate is placed in air at room temperature, the molecules in the metal will slow down while the molecules in the air will speed up.

Step-by-step explanation:

When a hot metal plate at 150°C is placed in air at room temperature, the molecules in the metal will transfer some of their kinetic energy to the molecules in the surrounding air through conduction. This will cause the molecules in the metal to slow down, while the molecules in the air will speed up. Therefore, the correct answer is: The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.
