Silicone is an orthoputic material that expands after being contained in a certain area for a certain period of time. That is why individuals who undergo cosmetic surgery often have to remove or change them because silicone will continue to expand (and while in the body) will explode.
What else can I help you with?
What happens when heat is added to silicon?
An intrinsic (pure) silicon crystal at room temperature has sufcient heat (thermal)energy for some valence electrons to jump the gap from the valence band into theconduction band, becoming free electrons.
Does halides contain silicon?
Yes, halides can contain silicon. Silicon can form halides by combining with elements such as fluorine, chlorine, bromine, and iodine to create silicon halides. Examples of silicon halides include silicon tetrafluoride (SiF4) and silicon tetrachloride (SiCl4).
What does silicon smell like?
Silicon itself is odorless. However, certain compounds containing silicon, such as silane or silicon tetrachloride, have distinct, unpleasant smells.
What is the compound for the formula SiCl4?
Silicon tetrachloride is the name of the compound SiCl4.
How many silicon atoms are in a basic silicon-oxygen tetrahedron?
How many silicon atoms are in a basic silicon-oxygen tetrahedron?i am thinking about 4..
What two pure substaces expand when frozen?
1. water 2. silicon 3. bismuth 4. antimony 5. gallium pick two.
Does solid food expand or contract when frozen?
If the food has water in it then it will expand.
Does iron expand when frozen?
no it don't
Why does breast milk shrink when frozen and expand when thawed?
Any liquid or solid shrinks when frozen; the molecules contract. Molecules expand when thawed.
By what percentage does water expand when it is frozen?
poo
Does apple jiuce expand when frozen?
Yes
Does oil expand when frozen?
by 'the law of non-compress ability of liquid' a liquid can neither be compressed nor be expanded. Between 3'C and 0'C water does expand with a decrease in temperature. Water at 3'C is the densest; water at 0'C is the lightest. This is the only interval for Ice I on which it expands with decreasing temperature.
Why is water the only substance that expands when frozen?
Nope. Silicon(Si), Gallium(Ga), Antimony(Sb), Bismuth(Bi) and acetic acid(CH3COOH, vinegar) all expand on freezing as well. Moreover, silicon expands more than water on freezing (10% compared to waters 8%). The trick to this is that any substance with an open tetrahedral molecular structure will also expand upon freezing. (Perhaps phosphorus oxide(s))
Do water expand when frozen?
yes, this is why if you put a filled to the brim cup of water in the freezer, it overflows when it is frozen....
Does jelly expand when being cooled and left to set?
No jelly does not expand because its particles are not being frozen.
Can you thaw frozen celery?
Yes, but the texture will be affected by water crystals that expand when frozen.
Why is frozen water less dense?
The water molecules expand when the temp. drops.
