State whether the following statements are true or false.Aluminium wire and mercury are two substances which expand on heating.

Accepted Answer

Concept- Matter exists in four different states: solid, liquid, gas, and plasma. States exist in matter. Make use of the thermodynamics idea. Almost all materials expand when heated. To quickly grasp, use common instances.
We are all aware that a variety of substances expand when heated. As a result of changes in the outside temperature, materials have a tendency to change their state or characteristics. Almost all matter in our cosmos expands. Water and air are two examples because they expand because their densities drop and their volumes rise.
The following are two examples:
1. Water
2. Air
The primary cause of expansion after heating is that when heat is applied to a substance, the material's particles become excited about absorbing energy since heat may act as energy. It becomes unstable after using up energy, moves, and tries to separate from one another.
When particles in a solid are closely packed together, it is difficult for them to travel from one location to another. Liquid particles are less tightly bound to one another and therefore less dense. Particles are significantly more free in gases, thus the density is lower. Additionally, gases demand less heat and energy than solids. Because gas particles are already separated and have a lot more freedom to move, gases expand the most when heated while solids shrink the least. Many compounds expand when heated and come into contact when cooled.
Hence, the given statement is true.
