Hello, attention passengers. Just to remind you that it is advisable to eat something sweet at this time.
Excuse me but... why do we have to eatsomething sweet?
Oh, I will explain you right now. It's because of Boyle's Law.
Boyle’s Law states that the absolute pressure and volume of a given mass of confined gas are inversely proportional, provided the temperature remains unchanged within a closed system. In other words, it means that if the pressure increases, the volume decreases and vice versa.
When the plane takes off or lands, there is an increase in altitude. This causes the air pressure to become low and high, and then this causes a variation on the outside and inside of the ears.
But chewing on something sweet helps the air in your ears escape through your throat.
Thank you for the information!
0mg! After so many years I finally understand the purpose.
