How can you cause more solid solute be dissolved in a liquid?
To dissolve more solid solute in a liquid, you can increase the temperature of the solvent, stir or agitate the solution, increase the surface area of the solute by crushing or grinding it, or increase the pressure of the system if the solute is a gas. These methods help to overcome the forces holding the solute particles together and facilitate their dispersion in the solvent.
What three ways to increase the dissolving rate of a solid?
Surface Area/Quantity of Solvent, Temperature, and Agitation
How can you increase the surface area of a solid reactant?
It exposes more of the solid to whatever you want to mix it with so that whatever you are doing, whether it be a physical or chemical change, will take place more rapidly.
List five ways you could increase the rate of a chemical reaction?
Increase the temperature to provide more kinetic energy for the reactant molecules to collide. Increase the concentration of reactants to increase the frequency of collisions. Use a catalyst to lower the activation energy barrier for the reaction. Increase the surface area of solid reactants by grinding them into smaller particles. Increase the pressure for reactions involving gaseous reactants to reduce the volume and increase collisions.
Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on
How do you increase the rate of a reaction of a solid?
Grinding the solid into a powder increases the surface area and increases the rate of the reaction. Heating it would also increase the rate.
What does it mean to increase the surface area of a solid?
increase the surface area of a solid means to increase the area of solid
When you crush a solid do you increase or decrease surface area?
You increase the surface area
What is superficial expansion?
Superficial expansion refers to the increase in the surface area of an object without a corresponding increase in its volume. This can occur in materials like foams or dry powders when they are exposed to air or a gas, causing them to expand in size. It is different from volumetric expansion, which involves an increase in both surface area and volume.
How do you increase the number of collisions between molecules?
heating, stirring, surface area
What will increasing the surface area of a solid do to the dissolving rate of that solid?
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
What can be done to make a solid solute dissolve faster in liquid solvent?
Examples:- increase the temperature- increase the pressure- stir the mixture- grind the solid solute
What process solid change to gas?
The process of changing from a solid to a gas is called sublimation. In sublimation, a solid directly transitions to a gas without passing through the liquid phase. This is usually achieved by heating the solid substance to its sublimation point, where it bypasses the melting phase and goes directly into the gas phase.
The flat side of a three dimensional solid?
The flat side of a three dimensional solid is called the face. The total area of all of the faces is called the surface area.
What is the sum of the areas of all the surfaces of a solid called?
The sum of all the areas of a surface of a solid is called the 'surface area'.
Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on
Increasing the amount of solid have on the shape of heating and cooling curve?
it would have a longer plateo area because there would be more of the substance
