Ventilation Apparatus

Details:

• Used for demonstrating the concept of convection currents.
• Convection is a heat transfer mechanism where heat moves from one place to another through fluid currents.
• Demonstration: Place a lighted candle under one chimney, then use a smoke source over the other chimney to reveal the flow of convection currents.
• The consequences of ventilation can also be shown by covering the chimneys and removing, in various combinations, the corks in the side panels.
