write five examples to show forces of attraction and space , vibrations and vibration of particles
Answers
Matter in the gaseous state has both variable volume and shape, adapting both to fit its container. Its particles are neither close together nor fixed in place.In gaseous state, molecules are free to move in any direction ,So their inter-particle space is maximum and their interparticle force of attraction is least. Examples are water vapour, nitrogen, oxygen are said to be gaseous state.
SOLID STATE - DEFINITION
Matter in the solid state maintains a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place.In solid state, molecules are compact and they move /vibrate about their mean position, So the inter-particle space is minimum consequently their inter-particle force of attraction is maximum.
Examples are apple, pen, pillow are said to be in solid state.
LIQUID STATE - DEFINITION
Matter in the liquid state maintains a fixed volume, but has a variable shape that adapts to fit its container. Its particles are still close together but move freely.In liquid state, molecules can move within the liquid , So their inter-particle space is more compared to solid and their interparticle force of attraction is less compared to solid.
Examples are water, coffee, beverages are said to be liquid state
FORCES OF ATTRACTION - DEFINITION
In liquids,The intermolecular attractive forces are strong enough to hold molecules close together.
In solids, The intermolecular forces between neighboring molecules are strong enough to keep them locked in position.
In gases, The lack of any significant attractive force between molecules allows a gas to expand to fill its container.
SPACE BETWEEN PARTICLES - DEFINITION
In solids,they are not easily compressible and have little free space between particles.
In liquids,they are not easily compressible and have little free space between particles.
In gases,they are compressible and have lots of free space between particles.
REASON BEHIND CONTINOUS MOTION OF PARTICLES - DEFINITION
Particles of matter are continuously moving. They possess the kinetic energy. As the temperature rises, kinetic energy increases and particles moves faster.
