Examples of soft and hard objects

📚 Quick Study Guide

• 🧱 Hard objects resist deformation when force is applied. Examples include rocks, metals, and wood.
• 🧸 Soft objects easily deform when force is applied. Examples include cotton, clay, and rubber.
• 📏 Hardness can be measured using scales like the Mohs hardness scale.
• 🌡️ Temperature can affect the hardness of some materials (e.g., metal becoming softer when heated).
• 🔍 The arrangement of molecules within an object impacts its hardness.
