IPA FISIKA : Percobaan Sederhana Konveksi Udara, Kertas Menari-nari (praktek fisika)

Summary

In this simple experiment, you’ll learn about air convection using wax paper and a candle. First, a spiral shape is drawn and cut from the wax paper, which is then placed on a support. When the candle is lit beneath the paper, hot air rises, creating a convection current that causes the spiral to rotate. This experiment demonstrates how heat drives air movement, a phenomenon that occurs in both nature and the atmosphere. Try it yourself at home to see this fascinating process in action!

Q & A

What materials are needed for the experiment described in the video?

You will need wax paper, matches, a candle, and a support such as an iron tip.

What shape should be drawn on the wax paper for the experiment?

You should draw a spiral shape on the wax paper.

How should the spiral be prepared for the experiment?

After drawing the spiral, you need to cut it along the spiral line to form a loose roll.

Where should the spiral paper be placed during the experiment?

The spiral paper should be placed on a support, such as an iron tip.

What is the role of the candle in this experiment?

The candle is lit and placed under the spiral paper to create heat, which causes the air to rise and creates convection currents.

What happens when the candle is placed under the spiral paper?

The hot air from the candle rises, creating a convection current that pushes the spiral paper to rotate.

Why does the spiral paper rotate when heated by the candle?

The rotation occurs because the convection current caused by the rising hot air from the candle exerts a force on the spiral paper.

What scientific phenomenon does this experiment demonstrate?

This experiment demonstrates the phenomenon of air convection, where heat causes air to move.

How does air convection relate to larger systems in nature?

Air convection occurs in the atmosphere and many other systems in nature, playing a crucial role in processes like weather patterns and heat transfer.

What is the purpose of this experiment for the viewer?

The purpose is to illustrate how heat can cause air movement, providing a simple example of convection currents in action.
