Metal lids on glass jars can often be loosened by running hot water over them. Why does that work?
Running hot water over a metal lid on a glass jar causes the metal to expand slightly due to the heat, which can help break the seal it has with the glass jar. This expansion makes it easier to twist the lid open.
Why is a tightened lid on jar easier to remove when heated?
Heating the jar causes the air inside to expand, increasing the pressure. This added pressure helps to loosen the lid by pushing it away from the jar, making it easier to remove. Additionally, heating can also help to soften any sticky substances that may be causing the lid to stick.
What does soda have in it that removes corrosion?
Soda contains phosphoric acid, which can help to dissolve and remove corrosion on metal surfaces. The acidity of the soda helps to break down the rust and corrosion, making it easier to clean and remove from the metal.
How would glass be distinguished from the metal refuse?
Glass can be distinguished from metal refuse by its smooth and transparent appearance, in contrast to the solid and opaque nature of metal. Glass is also usually lighter in weight compared to metal refuse. Additionally, glass is not magnetic, which can be a distinguishing factor when trying to identify it from metal.
Why would holding a bottle with a metal cap loosen the cap under hot water?
As the metal cap and glass bottle heat up, they expand at different rates due to their different materials. The metal expands faster than glass, causing it to loosen under hot water. This is because the metal cap's expanding size creates less friction against the bottleneck, making it easier to unscrew.
What cools faster glass bottle or can?
Considering cans are metal and metal is a better heat conductor than glass (any cook will confirm that from years of burnt fingers) then I'd say GLASS would be able to cool quicker. It's easier for glass to loose thermodynamic energy than metal.
