Solid Liquid Liquid Gas Solid Gas The above examples are called — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

I need to analyze the phase transition sequence: Solid → Liquid → Liquid → Gas → Solid → Gas **Understanding the sequence:** The given transitions show matter changing between different states of aggregation (solid, liquid, gas) through various pathways. **Key observations:** 1. **Solid → Liquid** = Melting 2. **Liquid → Liquid** = No change (same state) 3. **Liquid → Gas** = Vaporization/Evaporation 4. **Gas → Solid** = Deposition 5. **Solid → Gas** = Sublimation **What these examples represent:** These are all examples of **phase transitions** or **changes of state/phase changes**. They demonstrate how a substance can move between solid, liquid, and gaseous states through heating or cooling. **Why B is correct:** The answer is **B: Phase Transitions** (or **Phase Changes**). These are processes where matter changes from one physical state to another while remaining the same substance. Each arrow represents a specific phase transition: - Melting (S→L) - Vaporization (L→G) - Deposition (G→S) - Sublimation (S→G) All are physical changes, not chemical changes, involving energy transfer during state transitions.
