How do the solvent particles break up from the solute?
When a solute dissolves it breaks apart into its individual particles. The solute and solvent particles mix together and become totally mixed up. That's why a solution is a mixture! As the solute and solvent particles become mixed up, no matter is lost. The overall mass stays the same.
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
What is a solution called when it has a lesser concentration of particles?
A solution with the same solute concentration as another (e.g. human body fluids) is called isotonic.
When does the diffusion reach equilibrium?
When there is continuous movement but no change
Why do you think heat would cause a solute to dissolve faster?
Heat makes the atoms of the molecules to move faster in a solution, thus making the solute to dissolve quicker. It's the same that occurs when you stir a solution using a spoon. You are mechanically speeding the process. By heating you are physically speeding the dissolution process.
Do solids and liquids diffuse at the same rate?
No. The particles in the solids have different mass as the particles in the liqiuds, so they diffuse at the different rate. but if their particles have the same rate, they will diffuse at the same rate.
Which gas from among methane and hydrogen will diffuse the fastest and why?
Hydrogen will diffuse faster. It's particles are smaller, so with the same kinetic energy they move faster.
Unlike in an ideal gas in a real gas A. all particles move in the same direction B. all particles have the same kinetic energy C. the particles cannot diffuse D. particles exert attractive forces?
D. particles exert attractive forces on each other

How does an increase in surface area help a solute dissolve more quickly?
Not necessarily just changing the surface area causes the rate to change. Changing the ratio of surface area volume changes the rate at which a solute dissolves in a solvent. If the surface area is larger and the volume of a solute is smaller or the same, then the rate at which the solute dissolves in a solvent increases. If the surface area is smaller and the volume of the solute is larger or the same, then the rate at which the solute dissolves in a solvent decreases.
How does a particular size affect a soluble solid?
The smaller the particles, the more quickly and easily they dissolve. A powdered solute will dissolve faster than a large piece of the same solute.

A solution with the same solute concentration as another (e.g. human body fluids) is called isotonic.
What factors affecting the rate of dissolving?
What factors affect the rate of dissolvingHow quickly a substance dissolves in a solvent is unknown. A teaspoon of table sugar will dissolve rapidly in a hot drink. The same amount of sugar will take much more time to dissolve in a glass of ice water. Similarly, table salt dissolves rapidly in water at room temperature. Large pieces of salt, like those used in home water softeners, dissolve much more slowly, which makes this type of salt ideal for use over long periods. The rate of dissolving is affected by three main factors:StirringTemperatureParticle SizeStirring Stirring a solution increases the rate at which a solute dissolves in a solvent. For example, you may have tried to make a soft drink by dissolving flavor crystals in a pitcher of water. The flavor crystals are the solute and water is the solvent. If the package of flavor crystals is poured into the water, dissolving begins, but clumps of powder may remain. To speed up the process, you probably used a spoon to stir the water with the flavour crystals. This results in a more uniform arrangement of flavor crystals and water particles makes dissolving occur more quickly. You can actually see the flavor crystals being stirred until they dissolve in the water. The end result is a solution, as all parts of the soft drink mixture look the same. Temperature Temperature affects the speed at which particles move. Particles move more rapidly at higher temperatures, as heat is transferred by the movement of the particles. Since the rate of dissolving depends on solute particles bumping into solvent particles, when the particles move more rapidly, more solvent and solute particles will bump into one another. In addition, the solvent particles at the edge of a piece of solute will more rapidly carry away the solute particles that they meet. This will quickly spread the solute particles throughout the solvent. With increasing temperature, most solutes dissolve more rapidly in most solvents. This explains, for example, why a teaspoon of sugar dissolves more quickly in a cup of hot tea then in a glass of iced tea.Particle Size Particle size also affects the rate of dissolving. Large particles take longer to dissolve than smaller particles of the same substance. For example, sugar cubes dissolve more slowly than granular sugar, and rock salt dissolves more slowly than table salt. Solvent particles must bump into solute particles for dissolving to occur. Particles of a solvent will contact solute particles at the surface of a clump or crystal of solute particles. Therefore, large pieces of a solute must be broken apart to enable solvent particles to come in contact with solute particles.
Which diffuse faster heavy particles or light particles?
In general lighter particles should diffuse faster than heavier particles, this could be extrapolated from the relationship to mass, volume, and energy. If we look at particles of all the same, ideal, substance, we would see that an object with less mass would be smaller but would also require less energy to move. That is, at the same temperature a particle of lower mass would move faster than a similar particle of heavier mass. We also see that smaller particles also maximize surface area/mass - this is also conducive to faster diffusion.
