The pressure difference and wind velocity difference between the bottom of a chimney and the top of the chimney ensure that smoke is blown away from the chimney. Which scientific principle explains this daily life event?

Correct option is B

Bernoulli's principle states that as the velocity of a fluid (liquid or gas) increases, its pressure decreases. In the case of chimneys, the wind velocity is higher at the top of the chimney, creating lower pressure. The higher pressure at the bottom pushes the smoke upward and out through the chimney. This principle helps maintain proper airflow.

Information Booster:

1. Chimney Functioning: Hot air rises due to being less dense, and Bernoulli's principle ensures effective smoke ejection.
2. Applications of Bernoulli's Principle:
   • Aerodynamics of airplane wings.
   • Flow of water in pipes.
   • Lift in kites and sails.
3. Scientific Importance: Helps understand fluid dynamics.

Additional Knowledge:

• Le Chatelier's Principle: Predicts how equilibrium shifts in a chemical reaction due to changes in concentration, pressure, or temperature.
• Archimedes' Principle: Explains buoyancy – any object submerged in a fluid experiences an upward force equal to the fluid displaced.
• Euler's Law: Describes motion in fluid dynamics but is not directly related to chimneys.
