With the help of experiment show convection current in
liquids
Answers
Answer:
experiment - in one hand take bell and dip it in a tub filled of water and then dip ur ear in the same tub them ring the bell in water them u will be able to hear the bell ring
Explanation:
When you comes to know first time about convection currents in water, it is difficult for you to demonstrate it. Today I will show you a very easy science experiment to demonstrate convection currents in water.
Apparatus Required for Convection Currents in Water Experiment :
A flask
Water
Burner
Tripod stand
Colored paper
A paper punch machine
Steps for Convection Currents in Water Experiment :
1. First of all fill the flask with water.
2. Take out circular bits of colored paper with the help of paper punch.
3. Drop some paper bits in flask and immerse them properly in water.
4. Put the flask over burner and heat for 5 minutes.
5. As the water heated, you will see the movement in paper bits due to convection currents in water.
Why Did This Happen?
When you put flask on flame, then the water at the bottom of the flask starts to heat. Hot water is always lighter than the cold water. Hence, the water starts to flow upward in the flask and the cold water of the upper surface starts to move down. These are called convection currents in water.
Your paper bits also starts to move up and down with these convection currents. This movement of paper bits continues till the entire water in the flask reached at same temperature.
