PLEASE HELP! Emma prepared two glasses of water at two different temperatures. She added a spoonful of table salt to the cold wa

ter in glass #1 and spoonful of rock salt to the hot water in glass #2. She observed that the spoonful of table salt in glass #1 dissolved faster than the spoonful of rock salt in glass #2. Based on this observation, Emma concluded that salt dissolves faster in cold water than in hot water. Do you think Emma's conclusion is correct?
A. No, the temperature in glass #1 is lower, which decreases the rate at which salt dissolves.
B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
C. Yes, a decrease in temperature increases the rate at which salt dissolves in water.
D. Yes, it is based on an experiment which showed that salt dissolves faster in cold water.

Answer:

The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Explanation:

For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.

So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.

Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
