WebMar 29, 2024 · Solids are of two types - Crystalline and Amorphous solids. Crystalline solids are hard and possess a definite geometrical shape. Amorphous solids are soft and do not possess a definite shape. Crystalline solids have a definite melting point whereas amorphous solids do not have a fixed melting point and soften over heating. WebJan 30, 2024 · Amorphous compounds melt gradually across a temperature range, whereas crystalline solids have sharp melting points. As a result, crystalline solids have specific temperatures of fusion, whereas amorphous solids do not. Isotropy and Anisotropy: Amorphous solids are isotropic.
