Question

Suppose a candle is burning, and wind is blowing on one side of the flame. Which principle explains why the flame bends toward the wind? A. Newton’s B. Pascal’s C. Bernoulli’s D. Archimedes’

Answer 1

When a candle is burning and wind is blowing it on one side of the flame, which causes the flame to bend towards the wind is an example of Bernoulli’s principle. The principle explain that the higher the speed, the lower the pressure becomes. When you blow against one side of the flame, you are creating an area of low pressure. The relatively high-pressure air on the other side of the candle will rush over to fill the area of low pressure that causes the flame to be pushed in the direction of the blowing.
