Hot glass can break in cold water because glass is a poor conductor of heat. When part of the glass is in cold water and part is not, the part of the glass in cold water will shrink much faster than the part not in cold water. When one part suddenly becomes much smaller than the other part, the glass breaks.
What else can I help you with?
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.
Which is what happens when we put a cup of hot water with dye on a glass of cold water?
When you put a cup of hot water with dye on a glass of cold water, the hot water will rise to the surface of the cold water due to differences in temperature and density. This creates a mixing or diffusion effect, causing the dye to spread and color the cold water as the two temperatures equalize.
Why does hot oil break glass and not hot water?
The boiling point of oil is higher than water and absorbs more heat .When hot oil is poured in a glass container the heat is conducted through the cold glass which expands and breaks while in hot water the heat energy absorbed is less and the glass heat is dissipated slowly to avoid sudden expansion.
What happens when you throw hot water outside when it is cold?
When I grew up in Fairbanks, Alaska, we would go outside when it was below -60 degrees Fahrenheit, and toss a glass of hot water into the air. If cold enough, the water droplets would crystallize in the air before hitting the snow. If not quite cold enough, water would hit the ground, and freeze in seconds.
Why does hot glass crack when placed under hot water?
Hot glass is less likely to crack than cold glass. It's down to the temperature difference. If the glass is colder than the water, its outside heats up, and expands. Glass is a poor conductor of heat so the inside doesn't get hot and expand nearly as quickly. This sets up strains in the glass, and because it's brittle, it cracks. .Hot glass may still have a sufficiently different temperature from the water to cause the same effect
If a hot piece of thick glass is dipped in cold water it breaks give reason?
When the hot glass is suddenly exposed to cold water, the outer layer of the glass cools and contracts rapidly, while the inner layers remain hot and expanded. This creates stress within the glass, leading to unequal distribution of forces and ultimately causing it to break.
Does cold or hot water break down soap better?
hot water.
How do you cut the bottom of a glass bottle?
To cut the bottom of a glass bottle, you can use a glass cutter tool to score a line around the bottle, then apply hot and cold water to create a clean break.
Why does the hot glass of a kerosene lamp cracks when wet with water?
The glass of a kerosene lamp while glowing is hot. When water falls on it, there is a sudden change in temperature, which causes the glass to break.
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.
Which water should be cold and cold when doing a old remedy for a pair of nested drinking glasses?
Put cold water inside the glasses. Dip the outer glass into hot water. The outer glass expands, the inner glass contracts.
Which is what happens when we put a cup of hot water with dye on a glass of cold water?
When you put a cup of hot water with dye on a glass of cold water, the hot water will rise to the surface of the cold water due to differences in temperature and density. This creates a mixing or diffusion effect, causing the dye to spread and color the cold water as the two temperatures equalize.
Why shouldn't you pour a hot liquid into a cold glass?
The hot liquid could crack a cold glass.
An old remedy for a pair of nested drinking glasses that stick together is to run water at different temperatures into the inner glass and over the surface of the outer glass which water will be hot?
The difference in temperature causes the inner glass to expand while the outer glass remains the same size, breaking the vacuum seal between them and allowing them to separate easily. It's important to be cautious with the hot water to avoid accidentally shattering the glass if it is too cold or thin.
Why does hot oil break glass and not hot water?
The boiling point of oil is higher than water and absorbs more heat .When hot oil is poured in a glass container the heat is conducted through the cold glass which expands and breaks while in hot water the heat energy absorbed is less and the glass heat is dissipated slowly to avoid sudden expansion.
How can I cut a glass bottle without breaking it?
To cut a glass bottle without breaking it, you can use a glass cutter tool to score a line around the bottle, then apply hot and cold water alternately along the scored line to create a clean break.
Why does a glass tumber containing hot water crack if you cool it by powering cold water on it?
Because you're cooling down, thus shrinking the glass, outside MORE than the inside (in contact with hot water)
