Sub Topic Name : Solid - Vapor Equilibrium |

Introduction
• Solid iodine sublimes to give iodine vapor and iodine vapor condenses to give solid iodine. • When there is a balance between the solid and vapor state, solid liquid equilibrium is reached.
Pre-Requisites:
Sublimation, vapor
Activity:
Balancing a see saw on its fulcrum. Balance a weight balance.
Real Life Question:
How does iodine
change into vapors?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| sublimation | sublimation Conversion of solid into gas. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Iodine pellets in a jar | Observe how iodine sublimates and iodine vapors are seen in the jar. |
Real life uses :
Drying a cloth in
cold winter. Simply hang the cloth outside and retrieve it later in a dry
state.
Places to visit :
Kitchen, playground.
Practical examples around us
| Examples | Explainations |
|---|---|
| See saw | To balance a see saw equal weights need to be on both sides of the fulcrum. |
What you learn in Theory:
