Why does a hot liquid in a jar dent the metal lid?
When hot liquid is added to a jar, it heats the air trapped inside the jar. As the air expands, it creates pressure which pushes against the metal lid, causing it to buckle or dent. This is due to the difference in pressure between the inside and outside of the jar.
What happens to the particles on the metal lid when it is run inder hot water?
When a metal lid is run under hot water, the particles in the lid gain kinetic energy and vibrate more rapidly due to the increased temperature. This thermal expansion causes the metal to expand slightly, which can create a looser fit around the jar's opening. As a result, the lid may become easier to remove as the gap between the lid and jar increases.
Can you pour boiling hot water in a mason jar and close the lid?
Pouring boiling hot water into a mason jar can be risky. While mason jars are designed to withstand high temperatures, sudden temperature changes can cause them to crack or shatter. If you do pour boiling water in, it’s best to leave the lid off until the jar cools to prevent pressure buildup, which could lead to the lid popping off or the jar breaking. Always exercise caution when handling hot materials.
