The correct option is 1 and 3 only
Explanation
Matter exists in three distinct physical states-solid, liquid, and gas-determined by the arrangement of constituent particles and the strength of intermolecular forces acting between them.
- Statement 1 is Correct: In solids, particles are held very close to each other in an orderly fashion. There is very little freedom of movement, which gives solids a definite shape and volume.
- Statement 2 is Incorrect: In liquids, the particles are close to each other (similar to solids), but they are not held in fixed positions and can move around. They are not far apart; rather, they possess enough energy to slide past one another, allowing liquids to flow while maintaining a definite volume. The description of particles being "far apart and moving very fast" applies to gases, not liquids.
- Statement 3 is Correct: In gases, the particles are far apart compared to those in solid or liquid states. The intermolecular forces are negligible, allowing for easy and fast movement, which results in gases having neither a definite volume nor a definite shape.
Key Takeaway: The primary distinction between the states of matter lies in particle arrangement: solids are tightly packed and ordered, liquids are close but fluid, and gases are widely separated with high kinetic energy.
