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.
What else can I help you with?
Which one is an insulator - copper coin aluminum ladder glass or water.?
Glass would be the insulator of the choices given. All the other items are metal (conductors) or water (minerals cause conductivity).
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.
Metal spoon is often placed in glass before pouring in boiling water why?
My mother didn't, actually, but if one's mother did, it was probably to start cooling it right away to reduce the chance that the glass would crack. The spoon draws away the heat and releases it to the air. So while you may need to pour boiling water over a teabag, it does what it needs to to the teabag and then quickly starts to cool.
What would happen to a cold empty glass if it was placed in a hot humid room?
Hmmm... I think this shld b a better ans. When in a cold room, the glass will contract. So, when taken out of cold room and placed in hot room, expansion will take place. As the glass has uneven surface, the process of expansion will cause the crack.
Why is it that sodium metal would not be a good material for drinking glasses?
Sodium is a very highly reactive metal:contact with water or anything containing water would release hydrogen gas which could ignitecontact with anything containing fatty acids (e.g. human skin) would turn the fatty acids to soapscontact with air would cause oxidation of the sodium and release of hydrogen gas (there is water vapor in air)If released hydrogen ignited the sodium metal would melt and run into things!!!etc.
What would we observe when we place a metal lid over a glass of hot drink?
Placing a metal lid over a glass of hot drink would result in heating up of the metal.
Can you use a metal rack in a glass dish?
I would never recommend metal racks in glass pans . Both conduct heat at different levels and can cause the glass to brake. Please use metal racks in your metal pans .
What would be a better beater for a triangle a glass stick or a wooden stick?
Glass would be the best, but even better would be metal. But you'll have to pay attention what type of glass that you get.
If the temp calls to bake 350 for metal what would you use for glass don't have a metal pan?
350 should bake about the sameas metal, just remember to cool glass before washing it.
Can sulphuric acid store in a metal can?
Sulfuric acid would eat through a metal can. It must be stored in glass.
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.
What type of evidence would be expected to have trace elements?
glass and metal objects
Would a glass or iron rod heat up first and why?
An iron would why because an iron is a type of metal and metal heats up quickly
What is the state of matter for sliver?
if your talking about a wood or glass or metal sliver, it would be solid
Could you store gunpowder in glass temporarily?
Metal or Glass would best, but for long term storage it would be best to keep it in the original container it came in. The original container would be specially made for the purpose.
Can baby can formula be recycled?
I guess that would depend on what you mean by recycled. If you mean turned into more baby food I would have to say no. Although if you mean composted and turned into dirt then I would defiantly say yes. The glass jar can be made into new glass and the metal lid can be make into more metal.
Which will freeze the most metal glass plastic paper and why?
The metal paper would freeze more because it is a good conductor hence easily lose heat.
