Interpretation: The microscopic and macroscopic process that takes place when a sample of water is heated from room temperature to
Concept introduction: The process by which liquid changes into vapor on heating to its boiling point is called as boiling. Boiling occurs when atoms (or) molecules of a liquid have the capacity to spread out sufficiently to change from a liquid to gaseous state, resulting in the formation of bubbles. The bubbles in a boiling liquid consist of molecules of liquid that has gained sufficient energy to change to the gaseous state.

Answer to Problem 14A
When the water is heated, the particles move faster and faster. As the temperatures reaches
Explanation of Solution
When the process of boiling occurs, the more energetic molecules turns to a gas, spread out and forms bubbles. The bubble rises to the surface and enters the atmosphere. It needs energy to change from a liquid to a gas.
The formation of bubbles takes place when the liquid reaches the boiling point. These bubbles come to the surface releasing water vapor. This happens because as heat is added, the molecules began to vibrate vigorously until they have sufficient energy to escape.
