Under which conditions will sugar most likely dissolve fastest in a cup of water?

Question

Bernhard White · Accepted Answer

If the cup of water contained hot water. Sugar will dissolve a lot slower if it was in room temperature and even slower if it was in cold water.

Bernhard White · Answer

Option (c) is the correct answer.Explanation:According to collision theory, more is the number of collisions more will be the rate of a reaction. Hence, faster will be the formation of products.Also, when we increase the temperature then particles will gain kinetic energy and hence, more number of collisions take place due to which rate of reaction will increase. More over, increase in surface area of a substance will lead to more number of particles participating in a chemical reaction. Hence, this will also increase the rate of a reaction.Thus, we can conclude that sugar crystals with stirring at will most likely dissolve fastest in a cup of water.

sugar crystals with stirring at 15°CExplanation:Rate of dissolution of solids in liquids depends on : 1.) Temperature: Increasing the temperature means more solute can be dissolved in the given amount of solvent because the energy of the solute particles increases and more it can interact with the solvent particles. The rate of dissolution of solid also increases in liquids.2.) Size of the solute particles: If the solute particles is present in smaller size, more it can be dissolved because this action takes place on the surface of particles and decreasing the size increases the surface area of the solute particles. Hence, increasing the dissolution.3.) Stirring: This process brings fresh solvent particles to come in contact with the solute particles and hence stirring increases the rate of dissolution.Thus the sugar is most likely to dissolve in the form of crystals which have large surface area and at high temperature of with stirring.

C. sugar crystals with stirring at 15oCExplanation:Solubility is the amount of solute that will dissolve in a solvent to form a solution. Solubility increases with increase in temperature. The increase in temperature increases the average kinetic energy of the solute and solvent molecules causing them to collide frequently. Also the increase in surface area of the solute increases effective collision between solute and solvent particles.

I think the answer is C) sugar crystals with stirring at 15 °C

Bernhard White · Answer

option CExplanation:just took test on e2020

Bernhard White · Answer

with stirring at 15 degreesExplanation:

Bernhard White · Answer

Heated, disruption (mixing the solution), large surface area ( the sugar is ground up, not in a cube)

Bernhard White · Answer

I believe the answer is sugar crystals with stirring at 15 degrees Celsius. Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two major factors that affect solubility are temperature and pressure. Temperature affects solubility of both solids and gases, but pressure only affects the solubility of gases. Increasing the surface area of solutes also increases the solubility.

Bernhard White · Answer

If the water is hot it will dissolve much more faster then if it was in room temperature or in cold water.
