If you used a metal key to scratch materials like wood, stone, or iron, softer materials like wood might scratch easily, while harder materials like stone or iron would be more resistant. The key's hardness relative to the material determines the ease of scratching.

The hardness of materials is relative, not absolute. It depends on the materials being compared. For instance, a material like rubber is harder than a sponge but softer than iron, demonstrating that hardness varies based on comparison.

Some materials are easier to scratch because they have a lower hardness, meaning their atomic or molecular structure is less resistant to deformation. Softer materials allow sharp objects to penetrate or mark their surface more easily than harder materials.

The property of materials determined by their ability to be compressed or scratched is known as hardness. Hardness measures a material's resistance to deformation, scratching, or indentation.

The property of materials determined by their ability to be compressed or scratched is known as hardness. Hardness measures a material’s resistance to deformation, scratching, or indentation. Softer materials are easily compressed or scratched, while harder materials resist these actions, making hardness a key factor in evaluating material durability.
