The particles of matter which possess kinetic energy are in the state of 1) Continuous motion 2) Discontinuous motion 3) Static 4) All the above B. Which of the following conditions should be altered to change the state of matter from state to another ? 1) Pressure 2) Volume 3) Temperature 4) All the above 9. What happens to melting point of solid when impurities are added to the pure solid ? 1) Melting point increases 2) Melting point decreases 3) Remains the same 4) None D. What will happen if molecules become free to slip over one another and flow ? I) Liquid turns into solid 2) Solid turns into liquid 3) Solid turns into gas 4) All the above 1. Absorption of heat energy during melting will increase the vibrations of molecules & t intermolecular forces will 1) Decrease 2) Increase 3) Remain the same Due to weakening of intermolecular forces in the process of melting point, the mo 4) None 2. start vibrating 1) Less vigorously 2) More vigorously 3) Remains the same 3.
