In this video, the creator explores the behavior of electric kettles when boiling alcohol, specifically ethanol. Initially, the prediction is that a kettle filled with ethanol will not turn off automatically like it does with water due to the lower boiling point of ethanol. However, through experimentation, it is observed that the kettle with ethanol does turn off, and the explanation delves into the design of kettles, including bimetallic strips and thermal switches, to understand why this happens. The video also mentions a sponsorship by CuriosityStream, a platform for curated documentaries and films.
Sure, here are the key facts extracted from the provided text:
1. The text discusses whether boiling alcohol in an electric kettle will cause it to turn off automatically when it reaches its boiling point.
2. Alcohol, specifically ethanol, has a lower boiling point than water.
3. The author predicts that a kettle full of ethanol will not turn off automatically.
4. The text mentions that vodka contains about 40% ethanol and 60% water.
5. The boiling point of water is 100°C (212°F), while the boiling point of ethanol is 78°C.
6. When a mixture of ethanol and water boils, the boiling point is somewhere between 78°C and 100°C.
7. The concentration of ethanol in the boiling mixture changes, getting closer to pure water as it boils.
8. The text discusses the design of the kettle and how it detects boiling using a bimetallic strip.
9. It mentions that the kettle's trigger temperature is significantly lower than the boiling point of water.
10. The text explores the behavior of another kettle without the tube mechanism.
11. There's confusion about how the second kettle works, especially with the lid on or off.
12. The author investigates a small hole in the second kettle and its potential impact on its operation.
13. The text briefly mentions the sponsor, Curiosity Stream, and its content categories and collections.
14. The author provides information about a promotional offer from Curiosity Stream.
15. The video ends with a call to subscribe and mentions the next video.
These are the factual points from the text without including any opinions.
