Which of the following will have a plane, axis and centre of symmetry? |
Pseudosolids True solids Supercooled liquid Liquids |
True solids |
The answer is 2. True solids. True solids have a regular arrangement of atoms or molecules, which gives them a definite shape and volume. This regular arrangement also means that true solids have planes, axes, and centers of symmetry. Pseudosolids, supercooled liquids, and liquids do not have a regular arrangement of atoms or molecules, so they do not have planes, axes, and centers of symmetry. Here is a table summarizing the properties of the four types of materials:
