Which mode of heat transfer is primarily responsible for the heating of water in a beaker placed on a burner?

Correct answer: Convection

Explanation: ✅ Correct Answer: C) Convection 📚 Explanation: Convection is the transfer of heat through the actual movement of particles within fluids like liquids and gases. When water at the bottom of a beaker gets hot, it becomes less dense and rises, while cooler, denser water sinks to take its place. This continuous circular motion creates convection currents that eventually heat the entire volume of water.
