Question

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
