Question 7 • Chemistry

A hot metal plate at 150 times degree C has been placed in air at room temperature. Which event would most likely take place over the next few minutes?

Answer
A
Molecules in both the metal and the surrounding air will start moving at lower speeds.
B
The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.
C
The air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up.
D
Molecules in both the metal and the surrounding air will start moving at higher speeds.

Explanation

Heat flows from the hotter metal plate to the cooler surrounding air. As the metal cools, its molecules move more slowly, while the air molecules gain energy and move faster; this matches choice A.
