  Complete Notes on Matter Properties & Measurement in Physics Visual explanation of physical properties of matter including mass, volume, density, and temperature using scientific instruments. - Dr.Sanjaykumar Pawar  📘  1.3 Properties of Matter and Their Measurement 1.3.1 Physical and Chemical Properties 🔹 1. What are properties of matter? Every substance has its own special characteristics . These characteristics are called properties . Example: Water is colorless Iron is hard and magnetic 🔹 2. Types of properties Properties of substances are divided into two main types : (A) Physical properties Can be seen or measured without changing the substance. No new substance is formed. ✳️ Examples: Colour (e.g., copper is reddish-brown) Odour (smell) Melting point (ice → water at 0°C) Boiling point (water boils at 100°C) Density (mass per unit volume) ⭐ Key point: ✔ Identity of substance remains the same ✔ Only physical form or state may c...

Visualizing Boyle’s Law: As the volume increases from 120mL to 180mL, the pressure drops from 1.2 bar to 0.8 bar at a constant 35°C. Internal Link   * Ideal Gas Law Overview: "Mastered Boyle's Law?
