What Is a Solid?

Solids are the most rigid state of matter. They occupy space and possess definite shapes and thermal energy. But what makes a solid different from other forms of matter? To answer that question, we need to define what a solid is. Read on to learn more about solids. Here are some definitions:

Solids are the most rigid state of matter

A solid is the hardest substance known to science. It is very dense and is not able to change shape when subjected to a force. Its molecules are locked into place and cannot move. In addition, a solid does not have a high kinetic energy, whereas a liquid can. As a result, solids are also the most dense of all matter states. However, they are only slightly denser than liquids.

They occupy space

You probably know that solids occupy space. These objects have mass and cannot be compressed. In the past, scientists have used solids to build structures such as houses. Bricks, for example, have a fixed volume and shape. Because of this, they can be weighed and measured. And unlike solids, liquids cannot be compressed or reshaped. So, why do solids occupy space? Here are some answers to that question.

They have definite shapes

While the volume of a liquid may change with temperature, the shape and volume of a solid do not. Liquids, on the other hand, tend to follow the shape of the container they are in. They have close-packed particles that can slide past each other. While gases can change in volume, they do not have definite shapes. Solids, on the other hand, have definite shapes and have a fixed volume.

They have thermal energy

Thermal energy is the fundamental characteristic of all solids, whether they are liquids or gases. It is a force exerted on the atoms of a solid to cause them to vibrate. Because the vibrations are small and rapid, they cannot be seen under ordinary conditions. Moreover, heat can change a solid from a solid to a liquid. Because of this, solids are considered thermal insulators.

They have specific heat capacity

The specific heat capacity of solids is the energy required to raise the temperature of a unit mass by one degree Celsius. These materials are also known as thermosolids. This is a general term that covers almost any substance, including chemical elements, alloys, solutions, and composites. It is important to understand that the specific heat capacity of solids may vary slightly, and a sample should be tested for accuracy before making a definitive statement.
