Question
When an iron rod is heated, it gets longer upon beating, this is because the particles in the iron rod:
- Change the shape
- Gets bigger
- Gets close together
- Move further apart
Hint:
Any form of energy excites the particles.
The correct answer is: Move further apart
- When an iron rod is heated, it gets longer upon beating, this is because the particles in the iron rod move further apart.
- All matter is composed of tiny particles called atoms. These atoms tend to move to higher energy levels in case any external stimulus appears.
- These particles get excited when heat energy is given to the iron rod. The electrons, in their structure, jump to a higher energy level. In doing so, they collide with each other and move apart. And when the iron rod is heated, it increases in length because of these moved apart particles.
The iron rod, on heating initially becomes red, then orange, and finally turns blue.
