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 surrounding the metal will speed up, while the metal molecules will slow down.

Step-by-step explanation:

The most likely event that would take place over the next few minutes when a hot metal plate at 150°C is placed in air at room temperature is that the air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down. This is because heat is transferred from the hot metal plate to the surrounding air through conduction. As a result, the air molecules gain energy and move faster, while the metal molecules lose energy and move slower.
