Where are endothermic and exothermic reaction used in industry?
Endothermic reactions are used in industries like pharmaceuticals for drug synthesis and in metallurgy for metal extraction. Exothermic reactions are commonly used in industries like power generation for fuel combustion and in chemical manufacturing for producing heat as a byproduct.
Is the chemical reaction for aluminum exothermic or endothermic?
The reaction of aluminum with oxygen to form aluminum oxide is exothermic, meaning it releases heat. This reaction is highly exothermic and is the basis for thermite reactions and fireworks.
What is sprue hole?
A sprue hole is a channel or passage in a mold through which molten material is poured to create a casting. It is used in metal casting processes to allow for the molten metal to flow into the mold cavity and fill it completely. After the material solidifies, the sprue is removed from the final product.
Is rusting metal exothermic or endothermic?
Rusting metal is an exothermic process because it releases heat as it occurs. This process involves the reaction of iron with oxygen in the presence of water to form iron oxide (rust), and this reaction releases energy in the form of heat.
What is molten materials?
Molten materials are substances that have been heated to their melting point, causing them to transition from a solid to a liquid state. This molten state usually exhibits high fluidity and can be poured or molded into different shapes before it solidifies again upon cooling. Examples of molten materials include molten metal, glass, and lava.
Is strong acid burning through metal exothermic or endothermic?
The reaction between a strong acid and metal is typically exothermic, meaning it releases heat. This is due to the transfer of electrons from the metal to the acid, resulting in the formation of ions and the release of energy.
Is the reaction of sulphuric acid and metal carbonate an exothermic or endothermic reaction?
The reaction of sulphuric acid and a metal carbonate is exothermic because it releases heat energy as the reaction proceeds. This is due to the formation of new chemical bonds in the products which are more stable than the reactants.

How does malton metal pour?
Molten metal is poured into a mold cavity through a sprue, which is a channel that allows the metal to flow evenly. The temperature of the metal is crucial to ensure proper flow and fill of the mold. After pouring, the metal solidifies and takes the shape of the mold, creating the desired metal part.
Which process is endothermic-roasting or calcination?
Roasting is an endothermic reaction while calcination is an exothermic reaction. Roasting involves heating a substance in the presence of oxygen, such as in the preparation of metal ores, while calcination involves heating a substance in the absence of oxygen to drive off volatile substances, such as in the production of lime from limestone.
How does high wind velocity can cause porosities in weld?
High wind velocity can cause rapid cooling of the weld pool, leading to the formation of porosities due to entrapment of gases as the molten metal solidifies. The turbulent air flow can also disrupt the shielding gas protection around the weld, allowing atmospheric gases to come in contact with the molten metal, resulting in porosity formation.
Does solid metal 'float' on molten metal?
No, solid metal typically sinks in molten metal due to its higher density. When a solid metal is placed on top of molten metal, it will usually sink until it reaches a point where its density is equal to that of the molten metal around it.
Is earth's mantle made of molten rock or molten metal?
metal maybe iron or nickel or both
