What else can I help you with?
Is plastics becoming brittle after being left in the sun endothermic or exothermic?
endothermic glad to see you're doing your homework (:
Can you put acrylic in the freezer?
Acrylic is the word for any of a number of plastics. Probably the most widely-known acrylic is Plexiglas. You can put them in the freezer if you like, but they will be more brittle when cold.
Are non-metals brittle?
yes,nonmetals are brittle and cannot be rolled into wires or pounded into sheets +++ Not at all. Synthetic plastics are non-metals, and while some are indeed brittle others are, well, plastic by the true definition of that term! Clay is a natural plastic, and not considered a metal although the clay-forming minerals include complex compounds of metals. Wood is not metallic - but that's not brittle unless dried completely.
Is plastic shatterproof?
There are many kinds of plastic. Some are rigid, or flexible. Some plastics become brittle if frozen and may shatter if dropped, or be damaged by long exposure to sunlight losing their colour. Some plastics, such as used in shatterproof rulers, are flexible enough to withstand being bent by schoolchildren.
Is nickel brittle?
No, nickel is not considered brittle. It is a ductile metal, meaning it can be stretched and formed without breaking easily. Nickel is commonly used in various applications due to its strength and resistance to corrosion.
Does plastic have brittleness?
Plastics can be designed to be very brittle or very tough and flexible. Polymethyl methacrylate is quite brittle for example.
Is stainless steel brittle?
Stainless steel is not considered brittle, as it is known for its strength and durability.
How would you describe a metal that has a yield strength and tensile strength that are the same?
Brittle
Is plastics becoming brittle after being left in the sun endothermic or exothermic?

What happens to the yield strength of steel when carbon is added?
It will be lowered with the result that the steel becomes more brittle.
Is copper brittle?
Copper is not considered brittle. It is known for its ductility, malleability, and high tensile strength, making it a valuable material for various applications like electrical wiring and plumbing.
Is helium strong or brittle?
Helium is a gas . . . it has neither strength nor brittleness.
Can you break plastic?
There are many types of plastic. Brittle plastic can be broken, and softer plastics can usually be cut with scissors or a saw or sharp knife.
Is a plastics becoming brittle after being left in the sun a exothermic or endothermic?
The process of plastics becoming brittle after being left in the sun is typically an exothermic reaction. The heat from the sun causes the molecules in the plastic to break down, leading to a change in its physical properties.
Stress strain curve for brittle material?
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
What sort of properties do materials which show brittle fracture have?
Their breaking strength is smaller than their shear strength. Once the strain on the material surpasses the elastic limit, the material will fracture and in process known as brittle fracture. This plastic deformation is permanent and irreversible.
What types of elements are often brittle?
Many metals, such as cast iron, ceramics, and certain polymers are known to be brittle. They lack the ability to deform plastically and instead fracture easily under stress. Examples include glass, carbon fiber, and some types of plastics.
