SUMMARY

The discussion centers around the phenomenon of a milk cooker falling off a stove after being tightly closed overnight. Sundar suggests that a vacuum may have formed inside the cooker due to the cooling of the milk, which could have caused the lid to break free and subsequently displace the cooker. The possibility of external forces, such as someone accidentally knocking it off, is also considered. The conversation highlights the effects of temperature changes on closed systems and their physical implications.

PREREQUISITES
  • Understanding of thermodynamics, specifically the principles of vacuum formation.
  • Knowledge of the physical properties of liquids and gases under temperature changes.
  • Familiarity with the mechanics of pressure and force in closed systems.
  • Basic concepts of heat transfer and its effects on materials.
NEXT STEPS
  • Research the principles of vacuum formation in closed containers.
  • Study the effects of temperature changes on liquid and gas behavior.
  • Explore the mechanics of pressure and how it affects physical objects.
  • Investigate the thermal expansion and contraction of materials in cooking appliances.
USEFUL FOR

Individuals interested in physics, culinary science, or anyone seeking to understand the behavior of closed systems under temperature variations.

I boiled the milk in milk cooker and i opened once to take some milk out. Remaining milk was there in the cooker and cooker is tightly closed. I placed the cooker over the stove and stove is switched off.

when i get up in the morning, i can see that cooker has fallen down from the stove..is it some thing due to air get colder?.

cooker bottom is so flat, it can fall down with slightest touch..my doubt from where the slightest force is coming from?.

Thanks
Sundar

A vacuum may have formed in the container due to the cooling of the liquid/vapor in the closed system. Maybe the lid finally broke free due to the contraction and moved the pot off the stove. The walls of the pot could have also contracted due to the vacuum then "sprung" out when the vacuum was broken. Just a thought.
 
Are you looking for the cause of a container falling off your stove? Is it possible someone simply knocked it off?
