Which answer below correctly identifies the type of change and the explanation for the boiling of water? physical change because even though the change caused the temperature of the water to increase, the water’s physical properties remained exactly the same physical change because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved chemical change because gas formation was observed, which indicated that the water was transformed into a different substance chemical change because a temperature change was observed, which indicated that the water was transformed into a different substance
