This is due to molecular mobility, which changes with temperature. At colder temperatures, the molecules within a material may be less able to slip and slide past each other as they do at normal temperatures. At normal temperatures, the material will have a certain amount of elasticity or ductility and is able to deform under stress without a crack appearing. At lower temperatures, the elasticity or ductility is lost and when placed under stress, the material may crack and give rise to a brittle fracture. The temperature at which this change in material properties occurs is called the "glass transistion temperature" denoted as "Tg".
What else can I help you with?
Is mercury brittle?
Mercury is a liquid at room temperature and is not considered brittle. It is a poor conductor of heat, but it can shatter if it is frozen at extremely low temperatures.
Why does liquid nitrogen make things shatter?
When an object is immersed in liquid nitrogen, the extreme cold causes the material to rapidly contract and become brittle. Subsequent exposure to room temperature causes the material to quickly expand, leading to internal stress that can cause it to shatter.
What is negative 200 degrees celsius?
Negative 200 degrees Celsius is an extremely cold temperature. It is equivalent to -328 degrees Fahrenheit. At this temperature, substances would be frozen solid and extremely brittle.
Is germanium malleable?

What are examples of things that are brittle?
peanut brittle
Will a pencil break if frozen?
Yes it will. It will become more brittle and actually break easier than a pencil which is not frozen.
Is mercury brittle?
Mercury is a liquid at room temperature and is not considered brittle. It is a poor conductor of heat, but it can shatter if it is frozen at extremely low temperatures.
Can things that are frozen be warm?
No
Can a cheese roll be frozen?
Yep, all things can be frozen right?
What happens to rubber when its frozen?
Rubber becomes harder and less pliable as the temperature decreases until ultimately it actually becomes brittle.
Can POLYSTYRENE be frozen?
Yes, polystyrene can be frozen. Freezing polystyrene can help preserve food or keep it fresh for longer periods. However, extreme temperature changes can cause polystyrene to become brittle and potentially crack.
How do things get frozen?
when you freeze it in the fridge
What do you call when something is fragile beginning with br?
Brittle is a synonym for fragile. It begins with the letters br.
What is the function of the freezer?

Does a brittle star eat planton?
Yes, the brittle star eats plankton and a variety of things like: clams, oysters, mussels, plankton,krimps and sometimes bits of sponges!

No frozen things are dead and they don't come back to life.
