Matter is made of small particles of atoms or molecules. … The gas particles have big distances between them. Solid In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy.
Why Solid have maximum force of attraction between particles?
Solids have the maximum force of attraction between them because the interparticles spaces are very small due to which the intermolecular forces are very strong and thus creates the maximum region of attraction between the particles.
Which one has maximum force of attraction between its particles?
Detailed Answer :
(a) Solids have maximum force of attraction between the particles & closely packed.
In which state of matter the force of attraction between particles are strongest?
Solid usually have the strongest intermolecular forces when compared to liquids and gases. In solids, the particles are closely packed and this is why they are incompressible and have high density.
How do intermolecular forces of attraction vary in solids liquids and gases?
The molecules of a gas move apart when they collide. The average kinetic energy of the particles in a liquid (or solid) is small enough that the forces of attraction between them is sufficient to hold the particles close together. The molecules in a liquid (or solid) do not move apart.
Why do solids expand on heating?
When a solid is heated, its atoms vibrate faster about their fixed points. The relative increase in the size of solids when heated is therefore small. … Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.
Why do gases diffuse faster than solids and liquids?
The molecules of gas have more kinetic energy than liquid molecules and are smaller. … The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids. Therefore, gas particles have higher kinetic energy and travel more rapidly.
Which one has maximum movement of particles?
Among solids, liquids and gases; (a) A gas has maximum movement of particles.
Which state has highest force of attraction?
Solids have the highest force of attraction followed by liquid and then the gas has the least attractive forces. Therefore the particles of solid are closely packed and the particles of gas are free to move.
Which of the following phases of matter has the highest strength of attraction between particles?
Solid. In a solid, the particles (ions, atoms or molecules) are closely packed together. The forces between particles are strong so that the particles cannot move freely but can only vibrate.
Why are the intermolecular attractive forces stronger in liquids and solids than they are in gases?
“In solids, the intermolecular forces are very strong, and the constituent particles are closely packed. That is why; solids are incompressible and have high density. … In gases, the intermolecular forces are negligible (extremely weak), and the constituent particles are free to move.
Why do solids have higher melting and boiling points as compared to liquids and gases?
Solids have higher melting points than liquids or gases due to stronger intermolecular forces.
What forces hold solids together?
Solids are generally held together by ionic or strong covalent bonding, and the attractive forces between the atoms, ions, or molecules in solids are very strong. In fact, these forces are so strong that particles in a solid are held in fixed positions and have very little freedom of movement.
