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 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?
Are table salt and rock salt soluble or insoluble in cold and hot water without stirring?
Does surface area affect the rate of dissolving of a substance in water?
Does temperature affect the rate of dissolving of a substance in water?
What type of salt dissolves faster in water when stirred at different temperatures?
