Destiny is using a nutrient solution to use in her garden.She places the powder in a watering can.Then she adds the water.Which would dissolve the powder the fastest?
A.SHAKING THE CAN VIGOROUSLY
B.STIRRING THE SOLUTION SLOWLY
C.TILTING THE CAN CAREFULLY FROM SIDE TO SIDE
D.SETTING THE CAN DOWN AND LEAVING IT ALONE
See your post above.
A.shaking the can vigorously
d.setting the can down and leaving it alone
SHAKING THE CAN VIGOROUSLY
To determine which method would dissolve the powder the fastest, we need to understand the factors that affect the dissolution process.
The primary factors that influence the speed of dissolving a powder in a liquid are agitation, temperature, and surface area. Agitation refers to the movement or mixing of the solution, temperature affects the kinetic energy of the molecules, and surface area refers to the amount of powder exposed to the liquid.
In this scenario, the options provided are:
A. SHAKING THE CAN VIGOROUSLY: By shaking the can vigorously, you are applying a lot of agitation to the solution. This will help distribute the liquid and powder particles more evenly and increase the chances of contact between the particles, allowing for faster dissolution.
B. STIRRING THE SOLUTION SLOWLY: Stirring the solution slowly provides some agitation but not as much as vigorous shaking. This method may still result in the dissolution of the powder but at a slower rate compared to vigorous shaking.
C. TILTING THE CAN CAREFULLY FROM SIDE TO SIDE: Tilting the can carefully from side to side provides minimal agitation. While there will be some mixing of the liquid and powder particles, it may not be as effective as the previous methods in promoting fast dissolution.
D. SETTING THE CAN DOWN AND LEAVING IT ALONE: This method provides no agitation whatsoever. Without any movement or mixing of the solution, the powder particles will have limited contact with the liquid, resulting in very slow dissolution.
Considering the factors mentioned earlier, option A (shaking the can vigorously) is likely to dissolve the powder the fastest. The vigorous shaking will provide the most agitation and promote effective mixing of the powder and liquid particles, leading to faster dissolution.
It's important to note that the temperature of the water can also play a role in the dissolution process. Warmer water generally facilitates faster dissolution compared to colder water.
