The 5-liter boiler starts whistling when the water inside reaches its boiling point and begins to create steam. As the steam builds up pressure inside the boiler, it needs to be released to prevent the boiler from exploding. The whistling sound is produced by the steam escaping through a small opening in the boiler's lid, signaling that the water has reached its boiling point and the pressure is being released. **

Gasoline doesn't cost 5 euros per liter because the price of gasoline is influenced by various factors such as crude oil prices, refining costs, distribution and marketing costs, taxes, and exchange rates.

To compress a 5-liter beer keg, you would need to remove the air from the keg and then seal it tightly to prevent any air from getting back in. This can be done using a vacuum pump to remove the air and then sealing the keg with a tight-fitting lid or cap. Once the air is removed and the keg is sealed, it will be compressed and take up less space. Keep in mind that compressing a beer keg may affect the carbonation and quality of the beer inside. **
