What are the attractive forces in a liquid?
In a liquid, intermolecular attractive forces hold the molecules in contact, although they still have sufficient KE to move past each other. Intermolecular attractive forces, collectively referred to as van der Waals forces, are responsible for the behavior of liquids and solids and are electrostatic in nature.
What has the greatest force of attraction solid liquid or gas?
As the temperature continues to drop, the matter forms a solid. Due to the solid’s low kinetic energy, particles have no “time” to move around, the particles have more “time” to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction).
What are attractive forces?
1. attractive force – the force by which one object attracts another. attraction. affinity – (immunology) the attraction between an antigen and an antibody. bond, chemical bond – an electrical force linking atoms.
Do solids liquids or gases have stronger intermolecular forces?
Yes, intermolecular forces are the strongest in solids. In gases, the intermolecular forces are negligible (extremely weak), and the constituent particles are free to move. As a result, gases, can occupy any space available to them.”
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.
Why do gases diffuse faster than solids and liquids?
The molecules of gas have more kinetic energy than liquid molecules and are smaller. Fluid diffusion is slower because the particles move slower in a fluid. The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids.
What are the 2 types of forces of attraction?
There are two kinds of forces, or attractions, that operate in a molecule—intramolecular and intermolecular.
How do liquid and solids compared with gases in terms of attractive forces?
The particles in a liquid usually are still touching but there are some spaces between them. 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.
How do intermolecular forces differ 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.
