Which synthetic polymer get harder as the number of carbon atoms in the polymer chain increase?
Polyethylene gets harder as the number of carbon atoms increases.
What synthetic polymer gets harder as the number of carbon atoms in the polymer chain increase?
Polyethylene terephthalate (PET) is a synthetic polymer that becomes harder as the number of carbon atoms in the polymer chain increases, due to enhanced molecular packing and increased intermolecular forces. This property makes PET a suitable material for applications requiring stiff and rigid structures, such as in the production of plastic bottles and fibers.
Why does Cross-links between polymer chains increase the melting point?
Cross-links usually occur when a polymer molecule is at a larger size. A larger sized molecule is held together by stronger covalent bonds, and henceforth the force between the molecules is stronger. As the force between the molecules gets stronger, more energy is needed to separate them, meaning the melting point increases.
Why cementite is harder than austenite?
Cementite is harder than austenite because it is a compound of iron and carbon with a well-ordered crystal structure, whereas austenite is a solid solution of iron and carbon with a disordered structure. The ordered structure of cementite provides greater resistance to deformation and makes it harder.
How natural rubber can be made harder and stronger?
Natural rubber can be made harder and stronger through several processes, including vulcanization, which involves adding sulfur and heat to create cross-links between rubber molecules, enhancing elasticity and durability. Additionally, incorporating fillers such as carbon black or silica can improve strength and abrasion resistance. Chemical modifications and blending with synthetic rubbers can also enhance the overall performance characteristics, leading to a product that is both harder and stronger.
Which synthetic polymer get harder as the number of carbon atoms in the polymer chain increase?
Polyethylene gets harder as the number of carbon atoms increases.
Which synthetic polymer gets harder as the number of carbon atoms in the polymer chain increases?
Polymethyl methacrylate (PMMA), also known as acrylic, is a synthetic polymer that gets harder as the number of carbon atoms in the polymer chain increases. This is because longer polymer chains result in more extensive interactions between the polymer chains, contributing to increased strength and hardness.

What is differentiate between steel and Cast iron with reference to their carbon percentage and hardness?
iron with 1.5% of carbon by volume or less is called carbon steel and above 1.5% it is called cast iron, hardmess increases with the carbon % i.e. cast iron is harder than carbon steel
What happens if carbon dioxide content in a room increases?
Too much carbon dioxide will kill any animal or human. We need oxygen to live. As the levels rise, the need for air increases and a person will begin to breathe harder and deeper. If the levels get even higher, they will try to get out of the room or become unconscious.
How does the carbon content influence the hardness of carbon steel?
Increasing the carbon content in steel alloys causes the material to become harder. This is because the carbon sits in the interstitial sites of the lattice structure and hinders the movement of dislocation lines. This also increases the strength of the material but it decreases the ductility.
How does one tell the difference between a synthetic emerald and a natural emerald?
because natural emeralds are harder than a synthetic emareld
How does the volatility of a hydrocarbon change as its carbon chain length increases?
As the carbon chain length of a hydrocarbon increases, its volatility generally decreases. This is because longer carbon chains have stronger intermolecular forces, such as van der Waals forces, which make it harder for the molecules to escape into the gas phase. Shorter chain hydrocarbons are typically more volatile and have lower boiling points compared to longer chain hydrocarbons.
Is carbon fiber harder than a diamond?
no
How do you make polymer clay harder?
To make polymer clay harder, you can bake it in an oven according to the manufacturer's instructions. Ensure that the oven temperature is accurate and consistent throughout the baking process to prevent burning or cracking. Overbaking can cause the clay to become brittle, so it's important to follow the recommended baking time closely.
