Because of cross linking in the chains. This happens when heat is applied to the plastic. Once this has taken place thermoset plastics can not change shape or change to a thermosoft plastic.
Thermoset plastic with 18% glass refers to a composite material made up of thermosetting plastic resin and 18% glass fibers. The addition of glass fibers enhances the strength, stiffness, and thermal properties of the plastic, making it suitable for applications requiring these properties. This material is commonly used in automotive parts, aerospace components, and sporting goods.
Epoxy is a good example Or rubber. Basically any plastic that transforms with heat, and cant be transformed back. Thermosetting plastic or epoxy is a compond that when heated will cure and maintain it's shape even when heated again. Usually the compaound has to be mixed with hardeners and fillers then heated. Once cooled they will remain hard even if re-heated.
Cells with a cell wall.Because cell wall stiff shape cant be changed.
Liquids can easily change there shape because molecules are loosely bound to each other. in case of Solids, molecules are so tightly bound that you cant change it shape until you hit it with something. in case of Gases, you can say that molecules are almost free.
Paramecium have a rigid outer covering called a pellicle that limits their ability to change shape. Amebas, on the other hand, have a more flexible cell membrane that allows them to change shape easily in order to move and feed.
Thermosetting plastics are a type of plastic made of long, cross-linked molecule chains. Their structures are very rigid. Thermosetting plastics can be moulded and shaped when heated, yet they cannot be heated again after they set.
you cant
change the density by altering the shape.

You cant, weather is natural so you cant change it
Thermosoftening plastics are plastics that when heated, the polymers turn into a gooey kind of material which can then be put into a mould of whatever shape you wish the plastic to be. when it sets, you have your shaped plastic. thermosoftening plastics can be reheated and remoulded whereas thermosetting plastics cant be as the polymers for them, once moulded, cannot go gooey again because they have stronger chains between the polymers.
The sun will never change its size and shape, when the sun was created that's how it came out, no body can go to the sun and see whats there its just sun it has to be alt east half of the earth because it goes around 360 divide it by 2, and it would be half! that's why the sun size and shape cant change!
You cant. i remember playing that game but rly u cant change it
You cant! After you have made your account you cant change what you done!
