Plastics are organic polymers made from carbon, hydrogen, and other elements, whereas metals are inorganic elements that form crystalline structures. Plastics are lightweight, have low melting points, and are highly moldable, while metals are typically heavier, have higher melting points, and can conduct electricity. Additionally, plastics are generally more resistant to chemicals and corrosion compared to metals.

How are starch-based plastics being utilized in the development of sustainable packaging solutions?
Starch-based plastics are being used in sustainable packaging solutions as they are biodegradable and renewable. These plastics help reduce the environmental impact of traditional plastics by breaking down more easily in the environment. This makes them a promising option for creating eco-friendly packaging materials.
What are the key properties and applications of UV transparent plastics?
UV transparent plastics have the key property of allowing ultraviolet (UV) light to pass through them. This makes them useful for applications such as UV sterilization, UV curing of adhesives and coatings, and protection of sensitive materials from UV radiation.
Shiny malleable ductile and generally conduct electricity and heat are qualities of these.?

What is the thermal conductivity of diamond and how does it compare to other materials?
The thermal conductivity of diamond is very high, around 2,200-2,500 W/mK. This makes it one of the best thermal conductors among natural materials, far surpassing metals like copper and silver.
What makes mercury different than other metals?
Mercury is a metal but its unusual: at room temperature it is liquid
What makes plastics different from other engineering material metals and plastics?
Plastics are organic materials with low density, having low hardness, they are insulators, they are resistant to many chemicals, they doesn't resist to high temperature, they have poor thermal and electrical conductivity.
What metal makes aircraft?
Aluminium, steel and many plastics and composite materials.
Are non metals good thermal insulators?
Yes, nonmetals are generally good thermal insulators. Materials like rubber, glass, and certain plastics have low thermal conductivity, which means they do not easily transfer heat. This property makes them effective for applications requiring insulation, such as in building materials and thermal barriers. However, the thermal insulating properties can vary among different nonmetal materials.
What two properties of metal makes it suitable for over head cables?
Metalloids and non-metals make it useful for electrical-------------------------------------------------------------------------Metals are used in wiring to transfer the electrical energy around your home and non-metalic materials i.e plastics are used as insulators.
What material is pliable?
Pliable materials are those that can be easily bent, shaped, or molded without breaking. Common examples include rubber, certain plastics, and soft metals like aluminum. These materials are often used in applications where flexibility and adaptability are important, such as in packaging, insulation, and various crafts. Their ability to conform to different shapes makes them ideal for a wide range of uses.
Plastic conductor or insulator?
Plastic is typically an insulator. Its molecular structure does not allow the free flow of electrons, which makes it a poor conductor of electricity. However, there are some types of plastics that have been engineered to conduct electricity by incorporating additives or altering their structure.
What are the causes and effects of burn?
causes of burning non-biodegradable materials- It can makes our environment pollute. We must stop burning of non-biodegradable materials, such as plastics- it can make our environment polluted
Why do some metals conduct heat better than others?
Metals conduct heat better than non-metals due to the arrangement of their atoms, which allows for the free movement of electrons. In metals, electrons can easily move from one atom to another, carrying heat energy with them. This high electron mobility is what makes metals good conductors of heat.
How are starch-based plastics being utilized in the development of sustainable packaging solutions?
Starch-based plastics are being used in sustainable packaging solutions as they are biodegradable and renewable. These plastics help reduce the environmental impact of traditional plastics by breaking down more easily in the environment. This makes them a promising option for creating eco-friendly packaging materials.
What makes materials flexible?
Materials are considered flexible when they can bend or deform under stress without breaking. This flexibility typically arises from their molecular structure, which allows for movement and rearrangement of atoms or molecules. Factors such as the presence of polymer chains, the type of bonds (e.g., covalent or ionic), and the material's temperature can also influence its flexibility. In general, softer materials like rubber or certain plastics exhibit greater flexibility compared to rigid materials like metals or ceramics.
What makes th elements in the periodic table different?
Well some are metals and non-metals ( Which you should know dat ) and each has a different meaning.. To us. GabrielAk-47boy
What makes Mercury different from most metals?
It is in its liquid phase at standard temperature and pressure.
