Understanding Power Stations and Electricity Generation
Compare Both Power Stations:
Both of these are thermal power stations. The first is a nuclear power station that uses the heat of controlled nuclear reactions (breaking nuclei of uranium) to heat water and transform it into steam. The second is a thermal combustion station that uses the heat of burning petrol, natural gas, and coal to heat water and transform it into steam. Then, both thermal power stations use the steam to move a turbine. The turbine is connected to a magnet that produces alternating

Architecture: Ironwork and Architectural Techniques
Ironwork, particularly the way stone was cut, played a crucial role in shaping architectural techniques. Treatises on stonework led to transformations in walls, stands, arches, and covers.
Walls
Walls served a load-bearing function and were built to be gapless, except for designated access points. They were constructed using rigging, ensuring regular wear. The measurements of the stones varied, and different tools like chisels and hammers were used

Safe Handling of Explosives:
Definition: – Industrial explosives are mixtures of fuel and oxidizer that, when properly initiated, result in a chemical reaction producing an expansion and increased temperature at a very high speed.
General Characteristics of Explosives:
- Explosive Power: – The absolute power in a unit of weight and volume.
- Power-Breaker: – The ability to break rock.
- Detonation Velocity: – The speed of transmission of the blast.
- Density: – The concentration of explosive in a given volume.
Understanding Heat Engines, Refrigerators, and the Second Law of Thermodynamics
Heat Engine and Efficiency
- Any device that continuously converts heat into mechanical work is called a heat engine.
- For any heat engine, there are three essential requirements:
(i) Source: A hot body at a fixed temperature T1 from which the heat engine can draw heat.
(ii) Sink: A cold body at a fixed lower temperature T2 to which any amount of heat can be rejected.
(iii) Working Substance: The material that, upon being supplied with heat, will do mechanical work. - In a heat engine, the working substance

Oxy-Arc Cutting: Principles and Techniques
Introduction
The oxy-arc method is an oxygen cutting process where metal is cut by a chemical reaction with oxygen at high temperatures. This temperature is maintained by an electric arc between the electrode and the metal, as well as chemical reactions within the electrode itself. While exothermic cutting has become more prevalent, oxy-arc cutting remains a valuable technique with a long history and proven effectiveness.
This process is particularly well-
