Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through controlled heating and cooling.
Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.
The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, an...
Welding is a process of joining two or more metal pieces together by melting and fusing them.
Types of welding include MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), Stick, and Flux-Cored welding.
Welding can be done using different heat sources like gas flame, electric arc, laser, or ultrasound.
Common welding techniques involve fusion welding, resistance welding, and solid-state welding.

- Q1. What is the difference between diesel and petrol engine
- Ans.
Diesel engines use compression ignition while petrol engines use spark ignition.
Diesel engines use compression ignition, where the fuel-air mixture is ignited by the heat of high compression, while petrol engines use spark ignition, where a spark plug ignites the fuel-air mixture.
Diesel engines are more fuel efficient than petrol engines due to higher compression ratios and energy content of diesel fuel.

The resulting solution is cooled and filtered to remove impurities.
The purified solution is then heated to precipitate the alumina as a white powder.
The alumina powder is washed, dried, and calcined to produce pu...
- Q3. Reaction for Al extraction from alumina.
- Ans.
The reaction for Al extraction from alumina involves the reduction of alumina using carbon or electrolysis.
Alumina (Al2O3) is first converted into aluminum chloride (AlCl3) by reacting with hydrochloric acid.
The aluminum chloride is then reduced to aluminum metal by either carbon reduction or electrolysis.
In carbon reduction, carbon (usually in the form of coke) is heated with the aluminum chloride to produce aluminum ...
- Q4. Stainless steel production.
- Q5. Types of cast iron.
