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
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.
The second choice: physical change <span>because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved</span>
Fischer Projections allow to represent the three dimensional molecular structures in two dimensional environment without the change in the properties or the structural integrity of the compound. <u>It consists of horizontal as well as vertical lines both, where horizontal lines represent atoms which are pointed toward viewer while vertical line represents atoms which are pointed away from viewer. </u>The point of the intersection between horizontal and vertical lines represents central carbon.
