States of matter questions appear in almost every physics paper. Key exam scenarios:
- "Explain why the temperature stays constant during melting" (3 marks): Say energy breaks bonds → potential energy increases → kinetic energy stays constant → temperature stays constant.
- Heating curve interpretation (2-3 marks): Identify flat sections (state changes) and sloped sections (within-state heating). Label the melting and boiling points.
- Particle descriptions (3 marks): Describe arrangement, movement, and forces for each state. Always address all three aspects.
- Internal energy questions (2 marks): State that internal energy = kinetic + potential energy of particles.
