A simple example is to take 1 ice cube, which has 6 sides. Neatly cut the cube into 4 quarters (4 cubes). There are now 24 sides of the original single ice-cube exposed to the air, so melting should increase.

Which has a larger surface area powder or lumps?

Powder typically has a larger surface area compared to lumps because the fine particles in powder allow for more surface area to be exposed. This increased surface area can be advantageous for processes like absorption or dissolution.


What dissolves faster in a cold water crushed salt or rock salt?

Crushed salt dissolves faster in cold water compared to rock salt. This is because crushed salt has a larger surface area for water molecules to come in contact with, facilitating faster dissolution. Rock salt, on the other hand, has a smaller surface area which slows down the dissolution process.


How does surface area impact dissolution?

Surface area impacts dissolution rate by increasing the available area for the solvent to come into contact with the solute. A larger surface area means more solute particles are exposed to the solvent, allowing for a faster dissolution process. This is why powders dissolve faster than larger chunks of the same material.


What are the 5 factors that can affect the rate of a chemical reaction?

Chemists can control rates of reactions by changing factors such as surface area, temperature, and concentration, and by using substances called catalysts and inhibitors.A:Temperature, Concentration of the reactants, Catalyst, Surface area, the nature of the reactants, residence time and Pressure. A:But I have to clear this about the surface area factor to all.Heat IS a catalystOr the more the surface area exposed, the faster the rate of reaction?In my reference books and certain websites,the larger the surface area exposed, the fasterthe rate of reaction is stated.In my opinion, the correct one should be,the more the surface area exposed, the faster the rate of reaction.To support my opinion, this is my explanation;Hypothesis(my text/reference books) : The larger the surface area exposed,the faster the rate of reaction.The larger the surface area means thatthe bigger the size of the reactants.Let me take a cube, Cube A with 4cm sides.1 cube has 6 surface area exposed.4 x 4 = 16cm² ; 1 surface area is 16cm². [Larger surface area,but slower rate of reaction.= Doesn't support hypothesis.][Total surface area.]6 x 16cm² = 96cm²Now let me cut Cube A(same cube as before) into 4 equal pieces.Now there are 4 cubes; let each cube be Cube B.Then, each Cube B will be 2cm per side.2 x 2 = 4cm² ; 1 surface area is 4cm². [Smaller surface area,but faster rate of reaction.= Doesn't support hypothesis.][Total surface area of 1 Cube B.]6 x 4cm² = 24cm²[Total surface area of 4 Cube B's.]24cm² x 4 = 96cm² (To show that both cubes have the same mass.)Conclusion : The larger the surface area exposed, the slower the rate of reaction.Hypothesis is not accepted.If you use the term, larger in this condition,it is wrongly used.Hypothesis(my text/reference books) isthe larger the surface area exposed, the fasterthe rate of reaction.As we all know,the cube with the larger surface area exposed will react slowerthan the cube with the smaller surface area.Into my opinion, the more the surface area exposed, the faster the rate of reaction.I am describing the surface area exposed in terms of amount instead of size.Hypothesis(my opinion) : The more the surface area exposed,the faster the rate of reaction.Taking the same cubes, Cube A and Cube B's as mentioned above,Cube A ; 6 surface area exposed. [Less surface area exposed,slower rate of reaction.]Cutting Cube A into 4 equal pieces = 4 Cube B's.(1 Cube A = 4 Cube B's.)1 Cube B ; 6 surface area exposed.4 Cube B's ; 6 x 4 cubes = 24 surface area exposed. [Moresurface area exposed,faster rate of reaction.]Conclusion : The more the surface area exposed, the faster the rate of reaction.Hypothesis is accepted.it is temperature in general. not just heat. heat may be a catalyst but cold is not.


What is the surface area of sugar?

The surface area of sugar can vary depending on its form (granulated, powdered, etc.), but generally, the surface area of sugar crystals is calculated by determining the combined surface area of all exposed facets on the crystals. This measurement can be important in various applications such as food processing, where a larger surface area can impact dissolution rates and interactions with other ingredients.

Why does crushed ice melt fast?

Crushed ice has more surface area compared to a solid ice cube, which allows it to absorb heat more quickly from its surroundings. This leads to faster melting as the ice is exposed to a larger area where the surrounding temperature can transfer heat and cause it to melt.


Which will melt faster an ice cube or crushed ice?

Crushed ice since their is a greater surface area exposed.


Why does crushed ice melt faster than cubed?

let me put it in a simple way you crush it which makes it smaller so it melts quicker


Which melts fastercrushed ice or ice cubes?

Yes because crushed ice has a greater surface area to volume ratio that a cube of ice. The greater this ratio the faster heat energy is transfered to the frozen water this then causes the particles within the ice to vibrate faster so the ice turns into water faster.


How does the area of exposed surface affect evaporation?

The larger the exposed surface area, the faster the rate of evaporation, as there is more surface area for the liquid molecules to escape into the air. This is because more molecules are exposed to the air, increasing the likelihood of evaporation occurring. Conversely, a smaller exposed surface area will result in slower evaporation.


What is size of solute?

It is the amount of surface of a solute that is exposed to the solvent. The smaller the pieces of the solute are, the larger the surface area that is exposed to the solvent.


Does cubed or crushed ice melt faster?

Crushed ice melts much faster than cubed because crushed ice is smaller. Crushed ice melts faster because it has a larger surface area exposed to the air or liquid its in. It is also less dense and will be more subject to temperature change because of it.


Which has a larger surface area powder or lumps?

Powder typically has a larger surface area compared to lumps because the fine particles in powder allow for more surface area to be exposed. This increased surface area can be advantageous for processes like absorption or dissolution.


Who much of the substance is exposed on the surface?

The amount of substance exposed on the surface depends on the surface area of the substance. A substance with a larger surface area will have more exposed surface compared to a substance with a smaller surface area. Factors like particle size and shape can also affect the amount of substance exposed on the surface.


Why does water evaporate when the water is spread over a larger surface?

The area exposed to evaporation in the atmosphere is larger.


Why does crushed ice melt faster than the same amount of icein single block?

Crushed ice has more surface area exposed to the surrounding environment, allowing for faster heat transfer. This increased surface area allows the crushed ice to come in contact with more ambient temperature air, speeding up the melting process compared to a single block of ice with less surface area exposed.


A rock will weather faster after it has been crushed because it?

The crushed rock pieces have a greater surface area then whole rock giving more exposure to weathering.
