He drops the sugar cubes at the same time and then observes how much of them dissolves in two minutes. What will be the result of Sam’s experiment, and which statement should he use as his conclusion? A A greater amount of sugar dissolved in hot water because temperature is directly proportional to the solubility rate of sugar in water. B Temperature does not affect the solubility rate of the sugar cube in water because sugar dissolves equally in both cold and hot water. C A greater amount of sugar dissolved in hot water because temperature is inversely proportional to the solubility rate of sugar in water. D A smaller amount of sugar dissolved in cold water because temperature is inversely proportional to the solubility rate of sugar in water.Rt is 0.616 T is 37c G=G+RT * ln(k)
