Step 1

This is because the heat applied to the water causes it to change from a liquid state to a gaseous state, creating vapor. Therefore, the correct answer to part a is \textbf{iv. water vapor}. Show more…

Key Concepts

Water Vapor

Water vapor is the gaseous form of water that forms when liquid water is heated beyond its boiling point. The bubbles observed during boiling are primarily composed of water vapor created through the process of heating rather than a chemical reaction.

Physical Change

A physical change involves alterations in the form or state of a substance without changing its chemical composition. Boiling water is a physical change because the water molecules simply change phase from liquid to gas, forming water vapor.

Phase Transition

A phase transition occurs when a substance shifts from one state of matter to another, such as liquid to gas. When water boils, the transition from the liquid phase to the gaseous phase (water vapor) happens without altering the chemical makeup of the water.
