What produces the wavy effect in air over a hot stove?

Solution

To determine: The cause of wavy effect produces in air over a hot stove.

Answer:

The wavy effect in air over a hot stove is due to the varying density of air caused by the change in temperature of air.

Explanation:

When a temperature of a substance increases, its volume decreases while the mass remains constant, which results the density of a substance a decreases. If the temperature of the air increases, it reduces its density and makes it lighter so that the hot air moves upward and denser air takes the place of it.

The wavy effect of air of a stove is due to the varying temperature of air. Air near the stove gets heated and moves upward and cooled air takes the place of its. The hot air cools rapidly and again sinks down due to the hot stove. The mixing of hot and cold air results in to look like a wave.

Conclusion:

Therefore, the wavy effect in air over a hot stove is due to the varying density of air caused by the change in temperature of air.
