Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on
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.
What are the three ways to make a solute dissolve faster?
its very simple. Just increase the temperature of the solvent. this will increase its intermolecular space . So the solute will disolve quickly. or of course you could simply stir or shake them, add pressure or increase the surface area
Describe two methods to increase the rate at which a substance dissolve?
There are some solutes that dissolve fast. Some ways that you could quicken this proses is to stir it heat it shake it. When you do this you increase the rate at which the surfaces of the solute come into contact with the solvent. Increasing the area of contact between the solute and the solvent can also increase the rate of dissolving. Hope this helped !!! One of these methods is Temperature. When you stir or shake it, that increases the temperature. The other is...
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 is the increase in surface area of 1 meter square area of a solid for rise of temperature, 1kelvin is called the coefficient of surface expansion of material of that solid.
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?
Heating a solid enough will change it to gas. Or putting it in a less compressed area at the same tempterature. Or a combination of both.
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
