Reggie has a sample of raw sugar made up of large particles and a sample of white sugar made up of much smaller particles. He dissolved 1 tsp. of each sample in 1 cup of water. Which dissolved fastest?

a) Both dissolved at the same rate
b) The white sugar dissolved slowly, and the raw sugar dissolved quickly
c) The white sugar dissolved quickly, and the raw sugar dissolved slowly
d) The white sugar dissolved quickly, and the raw sugar did not dissolve.

To determine which sugar dissolved fastest, we need to understand the properties of sugar particles and how they interact with water.

Sugar is made up of molecules held together by chemical bonds. When sugar is added to water, the water molecules surround the sugar molecules and break the chemical bonds, causing the sugar to dissolve.

In this case, we have two samples of sugar: raw sugar with large particles and white sugar with smaller particles.

The rate of dissolution depends on the surface area of the sugar particles exposed to the water. Smaller particles have a higher surface area compared to larger particles, which means more water molecules can come into contact with the sugar and dissolve it quickly.

Therefore, we can conclude that the white sugar, with its smaller particles, dissolved more quickly than the raw sugar with its larger particles.

The correct answer is:
c) The white sugar dissolved quickly, and the raw sugar dissolved slowly.

I don't understand. Please could you give me the answer?. What do you think dissolved fastest for you?
