Detailed Solution

The above statement is true.
The materials that can be compressed by hand or bent into different shapes and can be scratched or cut easily are said to be soft. Rubber bands, erasers, leaf-cooked rice, and fresh chapati are categorised as soft materials. Materials that cannot be compressed by hand or deformed and cannot be scratched easily are said to be hard. Ice, pencil, pearl, wooden board, and pulses are hard materials.
