Emma prepared two glasses of water at two different temperatures. She added a spoonful of table salt to the cold water in glass #1 and a 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.

What question was Emma trying to investigate in her experiment? (2 points)
A: Are table salt and rock salt soluble or insoluble in cold and hot water without stirring?
B: Does surface area affect the rate of dissolving of a substance in water?
C: Does temperature affect the rate of dissolving of a substance in water?
D:What type of salt dissolves faster in water when stirred at different temperatures?
