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.

Please refer to your later post, which I saw first.

To determine which sugar dissolved the fastest, we need to understand how particle size affects the dissolution process.

When a solute, in this case, sugar, dissolves in a solvent, such as water, it is the individual particles of the solute that interact with the solvent molecules. The larger the surface area of the solute particles, the more solvent molecules can come into contact with them, resulting in faster dissolution.

In this scenario, Reggie has a sample of raw sugar made up of large particles and a sample of white sugar made up of smaller particles. When Reggie dissolves 1 tsp. of each sample in 1 cup of water, the difference in particle size will influence their dissolution rates.

Since the white sugar has smaller particles, it will have a larger surface area compared to the raw sugar, which means more water molecules can interact with the sugar particles. As a result, the white sugar will dissolve more quickly than the raw sugar.

Therefore, the correct answer is:

c) The white sugar dissolved quickly, and the raw sugar dissolved slowly.
