DIFFERENCES BETWEEN CRYSTALLINE AND AMORPHOUS SOLIDS Presented by: Crislyn Dorimon and Jaspher Pogado  WHAT IS SOLID? Solids are one of the fundamental states of matter, characterized by a fixed shape and volume due to their tightly packed particles. The arrangement of these particles defines their properties and behavior, dividing solids into two main categories: crystalline and amorphous. WHAT IS CRYSTALLINE AND AMORPHOUS SOLIDS? Crystalline solids exhibit a regular, repeating pattern called a crystal lattice, while amorphous solids lack this long-range order, resulting in distinct differences in their structure, properties, and responses to heat. Understanding these distinctions is crucial in exploring the behavior of materials in various scientific and practical applications.  DIFFERENCES BETWEEN CRYSTALLINE AND AMORPHOUS SOLIDS CRYSTALLINE AMORPHOUS ASPECT SOLID SOLID Particles are Particles are arranged in a arranged randomly Arrangement regular, repeating with no of Particles pattern (long-range long-range order order).

In contrast, amorphous solids have irregular or curved surfaces, and melt over a wide range of temperatures. THANK YOU
