Why does metal become more brittle after being heated then cooled?
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
Is brittleness chemical or physical propertie?
Being brittle is a physical property.
Which process changes liquid water into water vapor?
boiling will change all water being boiled fairly quickly into water vapor. Exposed water of any temperature will slowly become water vapor by way of evaporation.
What are the non example of brittleness?
biscuits peanut brittle eggshell coral osteoporosis
What property of nonmetals is the opposite of being mallable and ductile?

How does a leaf feel after being boiled in alcohol?

What happens to a boiled egg after being soaked in alcohol?
Not much, but if you soak it in vinegar the shell will dissolve!
Does alcohol react with plastic?
Yes, alcohol can react with certain types of plastic. Some plastics, such as polyethylene terephthalate (PET) and high-density polyethylene (HDPE), are resistant to alcohol and do not interact with it. However, other types of plastic, such as polyvinyl chloride (PVC) and polystyrene (PS), can be sensitive to alcohol and may degrade or become brittle over time when exposed to it. It is important to consider the type of plastic that is being used when storing or coming into contact with alcohol.
When was Being Boiled created?
Being Boiled was created in 1978-06.

What changes in the bone structure to cause them to go brittle?
What is referred to as 'brittle bones' is called osteoporosis. The change in the structure of bone that causes them to become brittle is a loss of bone density from a depletion of calcium. Think of Swiss cheese: it has holes in it. That is what osteoporosis looks like inside the bone. Instead of it being dense and filled with calcium, it has lots of holes in it, and so becomes weaker and more likely to break, or fracture.
