distillation of water working model for a science exhibition

Creating a distillation of water working model for a science exhibition is a great way to demonstrate the process of purifying water.

Here’s how you can make one using a glass flask with a stand, a plastic bottle to cool the distilled water, a DC water pump, and a glass cup to hold the distilled water:

Materials Needed:

  1. Glass flask with a stand
  2. Plastic bottle (cut in half)
  3. DC water pump
  4. Tubing or piping
  5. Glass cup
  6. Heat source (e.g., Bunsen burner, electric heater)
  7. Water

Step by Step Instructions:

  1. Set Up the Glass Flask:
    • Place the glass flask on a sturdy stand. This will serve as the container for heating the water.
  2. Connect the Plastic Bottle:
    • Cut the plastic bottle in with holes to circulate the cold water
  3. Install the Water Pump:
    • Attach the DC water pump to the plastic bottle’s cooling chamber.
    • Connect tubing or piping from the water pump to the plastic bottle, allowing water to circulate and cool the distilled water.
  4. Prepare the Distillation Process:
    • Fill the glass flask with impure water that you want to distill.
    • Position the glass cup beneath the plastic bottle’s spout to collect the distilled water.
  5. Heat the Water:
    • Apply heat to the glass flask using a Bunsen burner or electric heater. As the water heats up, it will begin to evaporate.
  6. Condensation and Collection:
    • As the water vapor rises, it comes into contact with the cooler surface of the inverted plastic bottle. This causes the vapor to condense back into liquid form and drip into the glass cup below, resulting in distilled water.
  7. Cooling and Circulation:
    • The DC water pump circulates cold water from the cooling chamber (plastic bottle filled with ice) through the tubing, helping to keep the condensation chamber cool and promoting efficient condensation of the water vapor.
  8. Observation and Analysis:
    • Observe the distillation process as the impurities are left behind in the glass flask, and pure water is collected in the glass cup.
    • Optionally, use a thermometer to monitor the temperature changes during the distillation process.

By following these steps, you can create a working model of water distillation for your science exhibition. This model effectively demonstrates the purification of water through the distillation process, highlighting the principles of evaporation, condensation, and cooling.
