Positive Feedback

The video tutorial explains a feedback loop using gasoline and fire, similar to a microphone and speaker setup. It describes how to start the reaction by heating gasoline, which has a low boiling point. The process involves the fire growing as the gasoline boils faster, creating a cycle. An unexpected outcome occurs when gasoline condenses and causes an explosion. The video concludes with the presenter's emotional reaction to the experiment.

What is the analogy used to explain the concept of a positive feedback loop?

• A spinning top

• A car engine

• A microphone and speakers

• A boiling kettle

What is the approximate boiling point of gasoline mentioned in the video?

• 20 degrees Celsius

• 40 degrees Celsius

• 100 degrees Celsius

• 60 degrees Celsius

What happens as the fire grows larger in the experiment?

• The tube melts

• The fire extinguishes

• The gasoline boils faster

• The gasoline cools down

What unexpected event occurs in the tube during the experiment?

• Gasoline condenses in the tube

• The tube changes color

• The tube breaks

• The tube expands

What is the final outcome of the experiment?
