Why does an empty glass cracks when you pour very hot water into it but does not crack if there is a metal spoon in it?
It will crack because like clay in a hot oven, if all the spots are not covered correctly, it will have a chance of cracking, but when the hot water gets into the crack, it will start to make it bigger. If the expansion is uneven, the glass will break and I don't understand why it won't break with a metal spoon.
What else can I help you with?
What is difference between cracks and fracture?
Crack a result over prolonged time as it occur due to inter-relationship with the preceeding and succeding criteria whereas fracture occur suddenly when there is an external force applied over it.
Why does glass not crack if a spoon is put into it?
It appears broken because of the reflection of the object and it's from the other molecules hitting the water which causes a bend like appearance to happen the light bends.the light bending is called refraction.
How much does an empty 50 gallon metal drum weigh?
An empty 50-gallon metal drum typically weighs around 30-40 pounds, depending on the thickness of the metal used in its construction.
Why vibrations in metal rod breaks glass?
When a metal rod vibrates at its resonant frequency, it can create extremely powerful standing waves that transfer energy to the glass. This energy transfer causes the glass to vibrate as well, eventually reaching its breaking point due to stress and fracture.
What makes a plane mirror a glass mirror?
A plane mirror and a glass mirror both reflect light due to their smooth and flat surfaces. The difference is in the material used to coat the back surface - a plane mirror has a thin layer of metal, while a glass mirror has a thin layer of metal deposited on the back side of the glass.
Why an empty glass cracks when you pour very hot water into it but it does not crack if there is a metal spoon in it?
As the metal spoon is a good conductor of heat and because heat travels from a hotter reigion to a colder reigion,the metal spoon will conduct heat away from the hot water and thus,the emty glass will not crack.
An empty glass cracks when you pour very hot water into it but it does not crack if there is a metal spoon in it?
The metal spoon has the capacity to absorb some of the heat of the very hot water, but not very much. It only makes a small difference.the crcking cracking crack
What does cracked meen?
A very small split in something such as glass, wood, or metal. Or crack can also be a type of drug.

Why do glass windows not fit into steel frames tightly?
If they did so then as the steel frames changed size as the metal they are made out of expanded and contracted with changing temperature the glass would crack. There need to be a gap to accommodate this.

What glue bonds glass to metal?
An epoxy will bond glass to metal.
What are vein minerals?
Metal deposits that occur in the cracks of rocks.
Explain why glass when heated cracks while metal does not?
Well, darling, when glass is heated, it expands unevenly due to its non-crystalline structure, causing stress that leads to cracking. Metal, on the other hand, is more flexible and can handle the heat without shattering like a delicate little snowflake. So, in short, glass cracks because it's a drama queen, and metal stays cool as a cucumber.
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.
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 .
