The white molten liquid observed during the collapse of the World Trade Center buildings was likely molten aluminum from the aircraft combined with burning building materials. The extreme heat generated by the fires could have caused this appearance, rather than it being thermite. Thermite is a specific incendiary material that requires precise conditions to produce.
Thermite is not an explosive. However, most types of thermite, especially copper, burns very hot and fast, and can splatter molten metal all over the place. It doesn't go boom like a pack of TNT, but it is still pretty dangerous.
When a substance is heated, it absorbs energy in the form of heat, causing its molecules to gain kinetic energy and vibrate more rapidly. Eventually, the substance's molecular bonds weaken, allowing the particles to move more freely and rearrange into a liquid state. This process is called melting.
Molten refers to a substance, typically a metal or rock, that has been heated to the point of melting and becoming liquid. It is the state of matter when a solid material transitions into a liquid form due to sufficient heat.
When thermite is ignited, it produces intense heat through an exothermic oxidation-reduction reaction. Adding oxygen and hydrogen to the mix could potentially react with the thermite, leading to a more explosive combustion. The hydrogen could react with the oxygen to form water, while the thermite reaction continues to generate high temperatures and release molten metal. Safety precautions must be taken when experimenting with these materials, as it can lead to a highly dangerous and uncontrolled reaction.
The noble metal commonly used in thermite reactions is aluminum. In these reactions, aluminum serves as the reducing agent, reacting with a metal oxide (like iron oxide) to produce molten metal and aluminum oxide. While aluminum is not a noble metal in the traditional sense (like gold or platinum), it is often considered in the context of thermite due to its high reactivity and role in these high-temperature reactions.
Pouring molten gold in a mold is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of the gold.
Yes. Gold would have to bond with something for it to be a chemical change.
Yes, pouring molten silver into a mold to make jewelry is a physical change. This process involves a change in the state of matter from liquid to solid without altering the chemical composition of the silver.
Copper thermite is a type of thermite where instead of the iron oxide, copper oxide is used instead. The reaction produces pure copper metal, but this thermite gets a little more splattery than the iron thermite.
The process is called casting. It involves pouring a liquid material, such as molten metal or resin, into a mold to create a sculpture or object.
Yes. "Molten" means the compound has melted into the liquid state. Anything that heat has melted into a liquid can be described as molten.
By definition, if something is "molten" it is a liquid.
Thermite is a mixture of aluminum powder and a metal oxide, commonly iron(III) oxide (Fe2O3). The chemical reaction can be represented by the equation: 2Al + Fe2O3 → 2Fe + Al2O3. This reaction produces intense heat and molten iron, which is the basis for thermite's applications in welding and metal cutting.

No. Molten rock is liquid.
The asthenosphere is partially molten. It is about 5% molten.
