What 3 advantages of using corn-based plastics instead of oil-based plastics?
Thermosetting plastics. Once cooled and hardened, these plastics retain their shapes and cannot return to their original form. Thermosetting plastics dont melt (i think) :)
Forensic evidence is typically placed in paper bags instead of plastics because paper allows evidence to breathe, preventing the growth of mold or bacteria. Plastic can trap moisture, potentially compromising the evidence. Additionally, paper bags provide a suitable environment for any trace amounts of chemicals to evaporate.
Plastic packaging takes hundreds to thousands of years to break down in the environment, depending on the type of plastic. Most plastics are not biodegradable and instead break down into smaller pieces, called microplastics, that can persist in the environment for even longer periods of time.
LPG is stored in iron cylinders because iron is a strong and durable material that can withstand the high pressure at which LPG is stored. Rubber and plastics may not be able to handle the pressure or may degrade over time when in contact with LPG, posing safety risks. Iron cylinders are also more fire-resistant than rubber or plastic, providing an added layer of safety.
Amorphous solids do not have a specific melting point because their structure is disordered, leading to a gradual softening as temperature increases instead of a distinct melting point like crystalline solids.
The advantages are that paper is better than plastic because it is stronger, cheaper, and they are non-biodegradable which means that they will hold up better. ~Devin~ has answered this question for ALL THE PEOPLE OUT THERE THAT DOES NOT KNOW
we can control the use of plastics by using paper bags instead of polythene bags, by recycling some plastics and using renewable resources.
What advantages did the Romans find in using a cross vault instead of a barrel vault?
Thermosetting plastics. Once cooled and hardened, these plastics retain their shapes and cannot return to their original form. Thermosetting plastics dont melt (i think) :)
Paper is made from renewable resources it is bio degradable and recyclable, most plastics are made from none renewable resources they are not bio degradable and most plastics are not or can not be recycled.
If you mean "as part of the machine" instead of "use the machine to work the plastic": The only real disadvantage is when the plastic chosen is the wrong one for the application, or if the part should have been made from something else instead. In some cases, plastics are exactly what you want to use.

cheaper
Thats what i am asking but u ask me to answer it instead?!?!?!?!
The advantages of using a conference chair instead of a regular chair include a more supported design and comfort. These chairs are also more accessible and more easily can be moved.
i dont know why
They help generate energy through water instead of using gases
