The answer is 2. Plastic is a non-metallic , meaning it is not a very good conductor of heat or electricity.
What characteristics is not a characteristic of plastic?
Plastic is chemically unreactive:Plastics do not react with air and water. Plastics are poor conductor of heat and electricity :They do not conduct heat or electricity,so they be used as insulators. Plastics can be moulded into different shapes.

What is the primary characteristic of plastic as a material?
Answer: Plastics generally have: resistance to corrosion and chemicals , low electrical and thermal conductivity, high strength-to-weight ratio, colors available in a wide variety and transparent, resistance to shock, good durability, low cost, are easy to manufacture, resistant to water and have low toxicity.
Which of the following is a characteristic of plastics?
Good transparency and wear resistance . Good insulation, low thermal conductivity. General formability, good coloring, low processing cost. Most plastics have poor heat resistance, high thermal expansion rate and easy combustion.
Which of the following is a characteristic of plastics Class 8?
Characteristics' of Plastics
Plastic is a poor conductor of heat and electricity . Plastic does not react with air and water and with many of the chemicals. Plastics are light weight, durable, cheap and very strong. Plastics are non- biodegradable substances.
What are the physical properties of a plastic bottle?
- transparency.
- flexibility.
- elasticity.
- permeable.
- water resistant.
- electrically resistance.
- Plastic is somewhat reactive to oxygen, over time it degrades as it is reacting to oxygen.
- generally plastic is soft.
What gives plastic different qualities and characteristics?
The name “plastic” refers to the property of plasticity, which is the ability to deform without breaking . Plastic is any synthetic or semi-synthetic organic polymer. In other words, while other elements may be present, plastics always include carbon and hydrogen.
What are the two types of plastics?
The two key categories of plastic are thermoplastics and thermosetting plastics (thermosets) . Thermoplastic products have the ability to be continually softened, melted and reshaped/recycled, for instance in injection molding or extrusion resins.
What are the characteristics of a material?
- Conductivity.
- Corrosion Resistance.
- Density.
- Ductility / Malleability.
- Elasticity / Stiffness.
- Fracture Toughness.
- Hardness.
- Plasticity.
Which of the following is a characteristic of organization?

- 2) High-Density Polyethylene (HDPE) ...
- 3) Polyvinyl Chloride (PVC or Vinyl) ...
- 4) Low-Density Polyethylene (LDPE) ...
- 5) Polypropylene (PP) ...
- 6) Polystyrene (PS or Styrofoam) ...
- 7) Other.
What are the five characteristics of plastic?
Plastics are generally low cost, easy to manufacture, durable, strong for their weight , electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.
Which of the following is a thermosetting plastic?
Answer: Bakelite is the thermosetting plastic in the given. Explanation: The material becomes very rigid and irreversible in nature when it is heated.
What are the characteristics of an ideal fuel?
- Fuel is easily available and cheaper.
- Burns easily in the air at a moderate rate.
- Releases a large amount of energy.
- No harmful substances must be emitted from fuel.
- Eco friendly.
What are the uses of plastic Class 8?
- Plastic are poor conductors of heat and electricity. So they are used to make covering of electric wires and handles of tools.
- Plastics are highly resistant to chemicals and water.
- Plastics are lightweight, strong and durable and are therefore used to make parts for aircrafts, cars etc.
