Which answer below correctly identifies the type of change and the explanation for the heating of copper sulfate pentahydrate? 1) physical change because even though the change caused the temperature of the copper sulfate pentahydrate to increase, the compound’s physical properties remained exactly the same2)physical change because even though gas formation was observed, the copper sulfate pentahydrate was undergoing a state change, which means that its properties are preserved 3)chemical change because gas formation was observed along with a color change, which indicated that the copper sulfate pentahydrate was transformed into a different substance 4)chemical change because a temperature change was observed, which indicated that the copper sulfate pentahydrate was transformed into a different substance
