What is thermostet plastic?
Thermoset plastic is a plastic material that can be molded and shaped. Applying the appropriate amount of heat to the material will cause a chemical change that will irreversibly cure it changing it to a hard material that can no longer be manipulated. This is different than other types of plastic materials which become softer and pliable whenever it is heated.
What name is given to a material that can be permanently deformed?
A material that can be permanently deformed is called a plastic material. This means that the material will undergo a change in shape that is not fully reversible after the deformation force is removed.
Can plastic forks be called utensils?
Yes, plastic forks can be called utensils. They are used that way, and the material out of which they are made dooes not, in this case, change their function.
How does heat change a material and can it change back?
Heat raises the temperature of the material. If the change is small then there is only a physical change and allowing the material to return to its original temperature will return it to its original physical state.However, too much heat can result in chemical changes which are usually not reversible. For example, if you heat a piece of plastic enough it will crumple into a charred mass. That charred mass will not return to the pristine plastic.
What was a quote from James t Russell?
James T. Russell is credited with saying, "Invention is a combination of brains and materials. The more brains you use, the less material you need."
When plastic deformation of a material occurs the material?
undergoes a permanent change in shape without fracturing. This occurs due to the movement of dislocations within the material that allow it to accommodate the applied stress.
Is corrosion of a marble statue is physical change?
no because all you are doing is changing the shape and form
What is a material that will permanently distorted called?
unelastic
Why does plastic turn white when you bend it, and what causes this change in color?
When plastic turns white when bent, it is due to a phenomenon called stress whitening. This occurs because bending the plastic causes tiny cracks to form on the surface, which scatter light and make the plastic appear white. The change in color is caused by the scattering of light due to the cracks, rather than a change in the actual color of the plastic material.
What is plastic behavior of a material under load?
It's when a material gets bent, squashed or otherwise changes shape to the point where it can't change back when the load is removed.
What is an invention that could change the world today?
the invention the could change the world would be the teleporter
