Why do plastics have a lower melting point than metals explain in terms of chemical bonding?
Plastics have weaker intermolecular forces such as van der Waals forces or hydrogen bonds, compared to the strong metallic bonds in metals. These weaker forces in plastics require less energy to break, resulting in a lower melting point. The strong and directional bonding in metals, on the other hand, requires more energy to break and thus they have higher melting points.
What type of element has a high boiling point and is a good electrical conduction?
metals
How does conduction take place in non metals?
In non-metals, conduction occurs through the movement of electrons within the material. When a voltage is applied, the electrons gain energy and move from atom to atom, carrying electrical conductivity through the material. However, compared to metals, non-metals generally have lower conductivity due to fewer free electrons available for conduction.
Why is conduction faster in metals?
Conduction is faster in metals because of the presence of free electrons within the metal structure. These free electrons can move quickly and easily through the metal, allowing heat to be transferred rapidly by conduction. Additionally, metals have a high thermal conductivity due to their crystalline structure, which further enhances their ability to conduct heat efficiently.
What is it called when free electrons in metals transferring energy by colliding with other atoms or electrons?
It is called thermal conduction, where free electrons in metals transfer energy through collisions with other atoms or electrons, facilitating the flow of heat throughout the material. This process is a key mechanism for heat transfer in metals.
Why are radiators metal?
Metals are a better heat conductor than plastics.
What is a hot plate a conductor or insulator?
A hot plate is typically a conductor. The metal coils inside the hot plate conduct electricity to generate heat quickly and efficiently. Heat conduction is better in metals compared to insulators like ceramics or plastics.
How does the electrical and heat conduction of metals and non metals compare?
Electrical and heat conduction is much greater in metals than in non metals.
What is the conduction of metal?
The conduction is transfer of heat between metals,also called metallic conduction
What are motorcycles made of?
Plastics and metals
What makes plastics different from materials like metals and plastics?
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.
What are game systems made of?
metals and plastics
How can conduction be helpful?
Conduction can cause a spark which can light a light bulb. Conduction can be used to heat up metals.
What elements are nonconducting?
if you mean the conduction of electricity then.... all non-metals do not conduct(excluding carbon which does conduct) all metals conduct although some conduct better than others
Is metals and iron and gold a conduction?
yes
What is a refrigerator made of?
Plastics, Metals, Glass, Carbons.
What is dirt bikes made out of?
metals, plastics and rubber
