Classifying the Boiling of Water: Physical or Chemical Change? Justify
Want To Learn More? To watch the entire video and ALL of the videos in the series:
This video tackles the classification of boiling water as either a physical or chemical change, examining the provided options. We conclude that boiling is a physical change, as the water's chemical composition remains the same during the transition from liquid to gas.

This discussion revolves around the classification of chemical bonds as ionic, polar covalent, or covalent based on the electronegativity difference between the atoms involved. The general criteria for this classification are explained: a difference greater than 1.7 indicates an ionic bond, between 0.5 and 1.7 signifies a polar covalent bond, and less than 0.5 designates a covalent bond. It then applies these criteria to four specific examples, including the CC bond in ethane (H?CCH?), the KI bo
