After heating the brick and the iron, it is observed that the brick heats up quicker and the brick releases energy quicker.
<h3>What is thermal energy?</h3>
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.
The iron has more energy than the brick even though it is at the same temperature. That means that the iron must have more particles than the brick.
Iron and brick are both solids and have the same volume, so the difference in total energy must be due to atomic composition.
