Why you squash a soild?

1. To reduce its volume. Squashing a solid reduces the space it occupies by forcing its particles closer together. This can be done for a variety of reasons, such as to make it easier to store or transport, or to increase its density.

2. To change its shape. Squashing a solid can change its shape, often making it more uniform or symmetrical. This can be done for aesthetic reasons, or to improve its functionality.

3. To increase its surface area. Squashing a solid increases its surface area, which can be beneficial for a variety of processes, such as heat transfer, chemical reactions, and adsorption.

4. To release trapped air or gases. Squashing a solid can release trapped air or gases, which can be necessary for safety reasons, or to improve the material's properties.

5. To test its properties. Squashing a solid can be used to test its properties, such as its strength, elasticity, and hardness. This can be done for quality control purposes, or to design materials with specific properties.
