Q1. Strength increase then hardness
Ans. 
Strength increase precedes hardness in materials due to the rearrangement of atoms and the formation of dislocations.
• Strength increase is typically achieved through processes like cold working, heat treatment, or alloying.

• Hardness is a measure of a material's resistance to deformation, while strength is its ability to withstand applied forces.

• For example, when a metal is cold worked, dislocations are introduced which i...read more

Q3. All the laws of thermodynamics and haet transfer in thermal engineering .
Ans. 
Thermodynamics and heat transfer are fundamental principles in thermal engineering, governing energy transfer and conversion.
• First law of thermodynamics: Conservation of energy, stating that energy cannot be created or destroyed, only transferred or converted.

• Second law of thermodynamics: Entropy always increases in a closed system, leading to the direction of heat flow.

• Third law of thermodynamics: As temperature appro...read more

Q5. All the process in RAC .
Ans. 
RAC stands for Refrigeration and Air Conditioning. It involves various processes like compression, condensation, expansion, and evaporation.
• Compression: The refrigerant gas is compressed to increase its temperature and pressure.

• Condensation: The high-pressure gas releases heat and condenses into a liquid.

• Expansion: The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature.

• Evaporati...read more

Q1. Tell about the difference between Normalizing and Quenching
Ans. 
Normalizing and quenching are heat treatment processes used to alter the properties of metals.
• Normalizing involves heating the metal to a temperature above its critical point and then cooling it in still air. This process improves the uniformity of the metal's grain structure and reduces internal stresses.

• Quenching involves heating the metal to a high temperature and then rapidly cooling it in a liquid, usually water o...read more

Q2. What are ferrous metals and and formulas
Ans. 
Ferrous metals are those that contain iron as their main constituent.
• Ferrous metals are magnetic and have high tensile strength.

• They are used in construction, manufacturing, and transportation industries.

• Examples include steel, cast iron, and wrought iron.

• The formula for steel is Fe+C, for cast iron is Fe+C+Si, and for wrought iron is Fe+C+Si+Mn.
