Question

Demonstrate the formation of convective currents.

Answer 1

Explanation:

Convection currents are generated by the differences in densities of the fluid that occurs due to temperature gradients. The activity that results from the continuous replacement of the heated fluid in the area of the heat source by the nearby present cooler fluid is called natural convection current.

Answer 2

You'll find that in all cases, the direction of smoke flow is different. Smoke movement patterns show the directions the cold and hot air travels in.

Explanation:

Currents of convection are placed in the air. Let us try the following experiment, to demonstrate their creation:

• In a beaker place a candle, and light it. Now light a stick of incense and bring it to the edge of the beaker's mouth. Observe the way the smoke flows.
• Now, follow the direction of smoke flow in a similar way by putting the stick just above the candle and then over the beaker at other regions.
• You'll find that in all cases, the direction of smoke flow is different. Smoke movement patterns show the directions the cold and hot air travels in.
