The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Statement**: The statement in question is "Solids can change into liquids on increasing the temperature." We need to determine if this statement is true or false. 2. **Heating Solids**: When solids are heated, the temperature of the solid increases. This increase in temperature affects the particles that make up the solid. 3. **Kinetic Energy and Particle Movement**: As the temperature rises, the kinetic energy of the particles in the solid also increases. Kinetic energy is the energy of motion, so as it increases, the particles begin to move faster. 4. **Effect on Particle Arrangement**: In solids, particles are tightly packed together. However, when the particles gain kinetic energy and move faster, they start to create spaces between them. 5. **Transition from Solid to Liquid**: As the particles move faster and the spaces between them increase, the solid begins to lose its rigid structure and can transition into a liquid state. This process is known as melting. 6. **Conclusion**: Since we have established that heating solids increases the kinetic energy of their particles, leading to a change in state from solid to liquid, we can conclude that the statement is true. ### Final Answer: The statement "Solids can change into liquids on increasing the temperature" is **True**. ---
