Amina mixed the following substances in two different glasses P and Q of the same
size.
P - 1 tablespoon of powdered sugar + 1 glass of water
Q - 1 tablespoon of common salt + 1 glass of water
Each time she measured the time required for the substance to completely dissolve in
water.
Which of the following can she find out based on the results?
A whether powdered sugar dissolves faster in water than normal sugar
B whether larger amounts of salt require more time to dissolve in water
C whether powdered sugar takes more time to dissolve than common salt
D whether common salt needs more water to dissolve than powdered sugar

Based on the results, Amina can conclude whether powdered sugar takes more time to dissolve than common salt. This directly addresses the comparison between the two substances. Therefore, the correct answer is C - whether powdered sugar takes more time to dissolve than common salt.

Final-Answer&Explanation:

Amina can find out the following based on the results:

A. Whether powdered sugar dissolves faster in water than normal sugar.

B. Whether larger amounts of salt require more time to dissolve in water.

C. Whether powdered sugar takes more time to dissolve than common salt.

D. Whether common salt needs more water to dissolve than powdered sugar.

First, let's analyze each point:

A. Whether powdered sugar dissolves faster in water than normal sugar:

Amina's experiment can provide some insight into this. If she has access to normal sugar as well, she can repeat the process with the same quantity of normal sugar and compare the time it takes for normal sugar to dissolve compared to powdered sugar. If the powdered sugar dissolves faster, she can conclude that powdered sugar dissolves faster in water than normal sugar.

B. Whether larger amounts of salt require more time to dissolve in water:

In Amina's experiment, she can start with one tablespoon of salt and then increase the amount gradually, making observations each time to see if larger amounts of salt take longer to dissolve in water. If the dissolution time increases with the amount of salt, then Amina can conclude that larger amounts of salt require more time to dissolve in water.

C. Whether powdered sugar takes more time to dissolve than common salt:

Amina's results can help her compare the dissolution times of powdered sugar and common salt. If she records that powdered sugar takes longer to dissolve than common salt, she can conclude that powdered sugar takes more time to dissolve than common salt.

D. Whether common salt needs more water to dissolve than powdered sugar:

Amina can vary the quantities of water while keeping the amount of substance constant and record the time it takes for complete dissolution. If she finds that common salt requires more water to dissolve than powdered sugar, she can then conclude that common salt needs more water to dissolve than powdered sugar.

Overall, Amina can draw these conclusions based on her observations from the experiments she has conducted. It's important to note that while these experiments can provide valuable information, the specific results would depend on the environmental conditions, temperature, and the quality of the substances used, so these findings may not be universally applicable.
