How can you demonstrate condensation of water by using glass, water and pieces of ice?

Answer»

Aim: 

To demonstrate condensation of water. 

What do we need?: 

A glass, water, and ice cubes.

How to do?: 

  • Take a glass half-filled with water. 
  • Wipe the glass from the outside with a cloth. 
  • Add some ice cubes into the water. 
  • Wait for one or two minutes. 
  • Observe the changes that take place on the outer surface of the glass.

What do we see? : 

  • Water drops appear on the outer surface of the glass.

What we learn?: 

  • The cold surface of the glass cools the air around it. 
  • The surrounded water vapour condenses and forms water droplets on the surface of the glass.
