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

Answer 1

Answer:

Physical change because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved.

Explanation:

Water boiling results in the physical state changing from solid to gaseous water. This moment can be called boiling or vaporizing, which is the change from liquid to gaseous state by heating water. Thus, the "Boiling Point" (PE) of a substance is the temperature at which that substance changes from liquid to gaseous state and, in the case of water, is 100 ° C. When the water reaches this temperature its physical change occurs because, despite the formation of gas, the water was undergoing a state change, which means that its original properties are preserved.

Answer 2

The second choice: physical change because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved
