Physics · Pedagogy of Science
Students are asked to observe a melting ice cube and a boiling kettle. They record temperature, shape change, and particle movement. The teacher explains that heating increases kinetic energy and causes changes in state. Students discuss how evaporation happens even without boiling, connecting particle theory to everyday life. Which factor is primarily responsible for changing the state of matter in this context?
- 1Color of the substance
- 2Type of container
- 3Change in shape due to pressure
- 4Change in kinetic energy of particles✓
