Are there any bad things about thermoplastics?
Thermoplastics can have lower temperature resistance compared to thermosetting plastics, meaning they might soften or deform under high temperatures. Additionally, some thermoplastics can be more prone to chemical degradation when exposed to certain solvents or chemicals.
Why is atmosphere absent in mercury?
Mercury has very high temperatures and is made up of hard rock. We are like a newborn baby - our planet can't resist such high temperatures, and that is why we have an atmosphere. Mercury can resist all that from the sun.
What is tropicalized air conditioning machines?
It is when an air conditioner can resist to high temperatures without breaking
What is chemical stability in relation to refrigeration oils?
These oils must resist to high temperatures and to oxidation.
What is chemical stability means in relation to refrigeration oils?
These oils must resist to high temperatures and to oxidation.

What kind of Plastics are Thermoplastics?
Thermoplastics are plastics that can be melted and recycled. Thermoplastics are used for many objects such as bottles, bags, records, hoses, clothes, containers, etc. There are a variety of different types thermoplastics and can have many different qualities to combat the environment. They are different from "thermosetting" plastics in this way.Thermosetting plastics are typically heated and compressed in a mold to achieve a desired shape or mixed from a resin and a hardener as used for composite material. When they are in contact with high temperatures they burn instead of melt, which is why they cannot be recycled. They are generally used for kitchen utensils like a spatula but are often used for telephones, computers etc.Thermoplastics:ABSVinylPETEPPPEHDPEPolyesterPSThermosetting plastics:Vulcanized rubberBakeliteDuroplastUrea-formaldehydeMelamine resinEpoxy resinPolyimides
What objects are sterilised at high temperatures?
Surgical instruments and babies' bottles are often sterilised at high temperatures to kill any harmful pathogens on the surface.
What is crucible cover and how it used?
a crucible is a small cup-like object used in chemistry because it can resist very high temperatures.
Would substances with low specific heat capacity also have high temperatures?
That depends on the surrounding temperatures. Objects tend to acquire the temperature of the surroundings.
How does the Arizona heat contribute to the melting of objects in its scorching temperatures?
The extreme heat in Arizona can cause objects to melt because high temperatures can weaken the molecular structure of materials, leading them to soften and eventually melt.
What are the benefits of thermoplastics?
More flexible than thermosetting plastics: they can undergo both elastic and plastic deformation without too much trouble. They can also be reformed and remoulded when reheated however they cannot withstand temperatures as high as thermosetting plastics.
