WATER RISING EXPERIMENT

          WATER RISING EXPERIMENT

Introduction :

     This is an experiment  which explains how the water rises when the candle puts off.

Materials Required :

Glass or tumbler

Candle

Tray

Food colour

Procedure:

Step-1:
              Pour  some water into the plate and               add some food colour in water..
Step-2:

Place the candle in centre of the plate in water and lit up the candle.
Step-3:

Invert the container on the candle.

Step-4:

         The candle puts off  and the water rises up into the container.



Conclusion :

     This happens because, when we cover the lit of the candle, it heats the air inside the container.The heated air expands and tries to come out. when the flame puts off the air in the container starts cooling down. As it cools the air contracts inside the container and pulls the water from outside the plate into the inverted container. In 5-10mins the water completely rises into the container.
