Why does a tight metal lid of a jar open easily when dipped in hot wat...
Explanation:
Expansion of metal:
When the tight metal lid of a jar is dipped in hot water, the metal lid expands due to the increase in temperature. This expansion causes the metal to slightly deform and loosen its grip on the jar.
Thermal expansion:
Metals expand when heated and contract when cooled. This phenomenon is known as thermal expansion. When the metal lid is heated by the hot water, it expands and becomes easier to open.
Breaking the seal:
The hot water also helps in breaking the seal created between the lid and the jar due to the contraction and expansion of the materials. This makes it easier to twist and open the jar.
Softening of the seal:
The heat from the hot water softens any material used for creating the seal, such as rubber or plastic. This softening allows the lid to twist more easily, further aiding in the opening of the jar.
Conclusion:
In conclusion, the tight metal lid of a jar opens easily when dipped in hot water because the heat causes the metal lid to expand, break the seal, and soften any sealing material, making it easier to twist and open the jar.
