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?
O Molecules in both the metal and the surrounding air will start moving at lower speeds.
O Molecules in both the metal and the surrounding air will start moving at higher speeds.
O The air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up.
O 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 around the metal will speed up, while the metal molecules will slow down.

Step-by-step explanation:

In this case, the most likely event to take place over the next few minutes is that the air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down. When a hot metal plate is placed in air at room temperature, heat energy is transferred from the plate to the air through conduction. This causes the air molecules around the plate to gain energy and move faster, while the metal molecules lose energy and move slower.
