(7 Questions)
- Q1. What is the second law of thermodynamics?
- Ans.
The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.
Entropy in a closed system tends to increase over time
Heat energy naturally flows from hot to cold objects
Efficiency of energy conversion processes is limited by the second law of thermodynamics
- Q2. What is the difference between creep and fatigue?
- Ans.
Creep is the slow, time-dependent deformation of a material under constant load, while fatigue is the weakening of a material due to repeated loading and unloading.
Creep is a time-dependent phenomenon, while fatigue is a cyclic phenomenon.
Creep occurs at high temperatures and constant stress, while fatigue occurs at lower temperatures and varying stress levels.
Creep leads to permanent deformation, while fatigue can lea...
- Q3. What is thermocouple?
- Ans.
A thermocouple is a temperature sensor that consists of two different metals joined together at one end, which produces a voltage proportional to the temperature difference between the junction and the other end.
Consists of two different metals joined together at one end
Produces a voltage proportional to the temperature difference
Commonly used in industrial applications for temperature measurement
- Q4. What is t-t-t diagram?
- Ans.
T-t-t diagram is a time-temperature-transformation diagram used in materials science to understand the transformation of phases in a material.
T-t-t diagram shows the relationship between time, temperature, and the transformation of phases in a material.
It helps in predicting the microstructure of a material based on the cooling rate and temperature.
T-t-t diagrams are commonly used in metallurgy to understand the phase
- Q5. What is annealing?
- Ans.
Annealing is a heat treatment process used to soften metals and increase their ductility.
Annealing involves heating a metal to a specific temperature and then slowly cooling it to room temperature.
This process helps to relieve internal stresses, improve machinability, and enhance electrical conductivity.
Examples of metals that are commonly annealed include steel, copper, and aluminum.
- Q6. What is the critical temperature of steel?
- Ans.
The critical temperature of steel is the temperature at which it loses its magnetic properties.
The critical temperature of steel is around 770°C (1420°F).
Above this temperature, steel becomes non-magnetic and undergoes a phase change.
The critical temperature varies depending on the type of steel and its composition.
- Q7. Types of steel?how we can differentiate them?
- Ans.
Types of steel include carbon steel, alloy steel, stainless steel, and tool steel. They can be differentiated based on their composition, properties, and applications.
Carbon steel contains primarily carbon and iron, with low amounts of other elements. It is commonly used in construction and manufacturing.
Alloy steel contains additional elements such as manganese, silicon, and copper to enhance its properties. It is use...

- Q1. What are the three laws of thermodynamics ?
- Ans.
The three laws of thermodynamics are fundamental principles in the study of energy and heat transfer.
First Law: Energy cannot be created or destroyed, only transferred or converted. For example, when a cup of hot coffee cools down, the energy is transferred to the surrounding air.
Second Law: Heat naturally flows from hot to cold objects, and entropy (disorder) tends to increase over time. For example, an ice cube melti...
- Q2. What is entropy
- Ans.
Entropy is a measure of disorder or randomness in a system.
Entropy increases as the system becomes more disordered.
It is a thermodynamic quantity that describes the amount of energy in a physical system that is not available to do work.
Entropy can also be thought of as a measure of the number of possible arrangements of a system.
For example, a messy room has higher entropy than a clean room because there are more possi...

- Q3. What is the natural of Project Work?
- Ans.
Project work is a collaborative effort aimed at achieving specific goals within a set timeframe.
Project work involves planning, executing, and monitoring tasks to achieve desired outcomes.
It often requires teamwork, effective communication, and time management skills.
Examples include developing a new product, conducting research, or implementing a new system.
- Q4. What is Blast furnace?
- Ans.
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron.
Used for smelting iron ores to produce iron
Consists of a furnace chamber with a tuyere at the bottom for air supply
Operates at high temperatures to melt the iron ore and extract the metal
Commonly used in the steel industry for producing pig iron
- Q5. What is Raw Meterial?
- Ans.
Raw material is the basic material used in the production of goods before being processed or manufactured.
Raw material is the starting material used in manufacturing processes.
It is unprocessed or minimally processed material.
Examples include wood, metal, cotton, and crude oil.
- Q6. Newton's Third Law?
- Ans.
For every action, there is an equal and opposite reaction.
Newton's Third Law states that for every action, there is an equal and opposite reaction.
This means that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
For example, when you push against a wall, the wall pushes back with an equal force in the opposite direction.
This law is fundament...
