When cut with a sharp-edged tool, which type of solids split into two pieces and the newly generated surfaces are plain and smooth?
Answer & explanation
Correct answer: option 1
Properties of cryastalline solids:
| Property | Crystalline solids |
| Shape | Definite characteristic geometrical shape |
| Melting point | Melt at a sharp and characteristic temperature |
| Cleavage property | When cut with a sharp edged tool, they split into two pieces and the newly generated surfaces are plain and smooth |
| Heat of fusion | They have a definite and characteristic enthalpy of fusion |
| Anisotropy | Anisotropic in nature |
| Nature | True solids |
| Order in arrangement of constituent particles | Long range order |
