What is the reason for this pattern of noise in electric kettles?
Asked 6 years, 11 months


It always seemed to me that the noise from electric kettles follows a
pattern: It starts low, then increases, and decreases again before the
water starts to boil.

___________________________________

The phenomenon you're noticing with boiling water is related to the way
heat is transferred and how bubbles form and collapse in the water.

Here's a breakdown:

1. Initial Boiling: When you first heat water, bubbles form at the
bottom where it's hottest. As these bubbles rise, they can create noise.
The sound is caused by the rapid movement of the water and the vapor
escaping.

2. Quiet Phase: As the water continues to heat and reaches a rolling
boil, the temperature stabilizes. The bubbles become more regular and
may not break the surface as dramatically, leading to a quieter sound.

3. Vapor Pressure: As boiling continues, the steam can create a layer
of vapor that insulates the water slightly, reducing the sound of the
bubbles breaking.


This process can vary based on the type of pot, the heat source, and the water's initial temperature.

As for proverbs, while there may not be specific sayings about the "loud
then quiet" nature of boiling water, many cultures have sayings about
patience and waiting, which can metaphorically relate to the boiling
process. The idea of something building up and then reaching a calm
state is a common theme in various expressions.
