The increased average kinetic energy keeps the molecules farther apart and moving around. This results in the increase of the average intermolecular distance. As mentioned above, the intermolecular attraction decreases.
What happened to the interparticle attractive forces with an increase in the distance between the particle?
The force of attraction between particles decreases as the distance between particles increases.
When distance between the particle are large the particles experience attractive force and aggregates are formed This is known as?
The pairwise interactions between these particles are often described by traditional colloidal Derjaguin–Landau–Verwey–Overbeek (DLVO) theory . Here, electrolyte ions in solution rearrange to form electric double layers near the charged surface of a particle.
Which is the option for matter in order of increasing distance between particles?
Hence, the increasing order of the interparticle distance in the three states of matter is solid < liquid < gas.
What happens to a substance when the space between its particles is decreased?
When the space between its particles is decreased, the volume of the substance also decreases because the space occupied by the substance is decreased.
How does the stored energy have effect on interparticle space?
Stored potential energy increases the space. State why the inter-particles attraction decreases to negligible. Answer: This is so because when distance between particles increases, and force of attraction decreases leading to Inter-particle attraction to almost negligible.
What is the effect of electrolyte on colloids Mcq?
The coagulation of a colloidal solution by an electrolyte does not take place until the added electrolyte has certain minimum concentration in the solution. The minimum concentration of an electrolyte in millimoles per litre required to cause precipitation of a sol in two hours is called coagulating value.
What is the effect of electrolyte on colloids?
An increase in the ionic strength above a region of relatively small electrolyte concentrations favours the phase separation of the colloid under otherwise identical conditions and causes the mutual diffusivity to markedly decrease, the more so the larger is the concentration of the particles.
What influences the motion of particles in gas?
In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster.
What are the forces of attraction between particles of matter?
Solution: The force of attraction between the molecules of matter is called the intermolecular force of attraction. It is maximum in solids, less in liquid and least in gases.
When the force of attraction between the molecules decreases the distance between the molecules?
The force of attraction between the particles decreases if the distance between them increases and vice versa. This is because according to coulombs law the force of attraction between two charged particles is inversely proportional to the square of the distance between them.
Is the space between the particles in the matter influences speed of diffusion explain?
yes,space between the particles influence the speed of diffusion. speed of diffusion is directly proportional to spaces between the particles. … example-gases have high intermolecular spaces than solid and liquid so they have fastest speed of diffusion than solid and liquid.
What is in the spaces of particles that make up matter?
There is nothing in the space between the particles that make up matter. The particles which make up matter are in constant motion in all physical states.
What happens to particles when they are compressed?
When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container. This force is called pressure. There are several units used to express pressure.
