Contrast the changes in a crystalline solid as it is heated to those in an amorphous solid that is heated?
As a crystalline solid is heated, it undergoes a well-defined melting point where its ordered structure breaks down to a disordered liquid state. In contrast, an amorphous solid softens gradually upon heating without a distinct melting point, as its structure lacks long-range order. The amorphous solid may eventually become a viscous liquid upon further heating.
Differentiate between cristaline solids and amorphous solids?
Crystalline particles form a regular repeating pattern, also when a crystalline solid is heated it melts at a specific temperature. Amorphous particles are not arranged in a regular pattern, and when it is heated, it may become softerand softer or change into other substances.
What is an amorphous when heated?
When an amorphous material is heated, it gradually softens and starts to flow like a liquid without a well-defined melting point. This behavior is known as glass transition, and it occurs because amorphous materials lack a regular crystalline structure that would normally lead to a distinct melting point.
What is the shape of an amorphous substance?
an amorphous substance is something that has a random molecular formation in it's natural form (when solidified). the opposite would be semi-cristaline which has random molecular structure when heated but returns to an organised unifom state when solidified. example. certain polymers
Why glass is not crystalline?
glass does not have a crystalline structure but it is still a solid. There are a few solids that don't have crystalline structure such as coal, a block of wood and a brick. Solids that do not have a crystalline structure are known as amorphous solids.

How do crystalline and amorphous solids differ?
Crystalline solids have a well-defined geometric structure with particles arranged in a repeating pattern, giving them a sharp melting point and distinct faces. On the other hand, amorphous solids lack long-range order in particle arrangement, leading to a more random structure. This results in amorphous solids having a gradual softening when heated compared to the sharp melting point of crystalline solids.
What is amorphous sulphur?
Amorphous sulfur is a non-crystalline form of sulfur that does not have a well-defined structure like regular crystalline sulfur. It is often produced by rapidly cooling molten sulfur, resulting in a more random arrangement of sulfur atoms. Amorphous sulfur can exhibit different physical and chemical properties compared to its crystalline form.
What is the glass transition of Teflon?
Teflon does not exhibit a distinct glass transition temperature, as it is a non-crystalline polymer. Instead, it transitions directly from a glassy to a rubbery state as it is heated due to its amorphous structure.
Rubber and glass which become softer as they are heated are examples of?
Rubber and glass which become softer as they are heated are examples of crystalline solids

Are rubber and glass when heated examples of crystalline solids?
No, rubber and glass are not crystalline solids when heated. Rubber is a type of amorphous solid, which lacks a specific arrangement of atoms, while glass can also be amorphous or have some degree of short-range order but not a long-range repeating pattern found in crystalline solids.
Does glass have a definite boiling point?
Glass does not have a distinct boiling point because it is an amorphous solid material that does not have a well-defined crystal structure. Instead of melting and boiling like crystalline solids, glass softens and then gradually transitions into a liquid state as it is heated.
A glass blower can bend and shape a piece of glass that has been amorphous solid?
Its an amorphous solid. When the glassblower blows into the glass, it expands just like a balloon. Crystalline solids can't expand like that because their atoms are held together in a rigid lattice. But amorphous solids have many of the proprties of liquids and can flow past each other, allowing the glass to stretch like the skin of a balloon.
Why glass is not crystalline?
glass does not have a crystalline structure but it is still a solid. There are a few solids that don't have crystalline structure such as coal, a block of wood and a brick. Solids that do not have a crystalline structure are known as amorphous solids.
