Fire and Water Experiment - Combined Gas Law (Chemistry)

Explore how temperature and pressure are related in gasses with the simple fire and water experiment. Great experiment when learning about the combined gas law. The reaction also yields fewer gas particles than it consumes. The majority of the change is due to the expansion and contraction of the gas due to the temperature change.

▶️ How to do the fire and water chemistry experiment:
Step 1: Fill an empty plate with water, nearly to the top.

Step 2: Add a drop or two of food coloring.

Step 3: Carefully place an unlit tea candle in the center of the water, allowing it to float.

Step 4: Light the tea candle.

Step 5: Carefully place an empty glass upside down over the burning candle, so that the rim of the cup is sitting in the water.

Step 6: Observe how the water reacts.

▶️ How the fire and water experiment works (demonstration for combined gas law):
The air coming off of the candle flame is over 1000 degrees Celsius. Once the candle flame goes out from a lack of oxygen, the air starts to cool down. This lowers the pressure inside the glass, allowing the higher pressure air in the room to push the water into the glass.
