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...read more

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...read more

Q1. Favorite subject, why? can rod temp. increase more than the fluid temp. in which it is immersed?
Ans. 
Yes, rod temperature can increase more than the fluid temperature due to factors like thermal conductivity and heat transfer.
• Thermal conductivity of the rod material plays a role in how quickly it absorbs heat from the fluid.

• Heat transfer rate between the rod and the fluid can also affect the temperature difference.

• If the rod has a higher specific heat capacity than the fluid, it can retain heat and increase in tempera...read more

Q2. Define convection , radiation
Ans. 
Convection is the transfer of heat through a fluid (liquid or gas) by the movement of the fluid itself. Radiation is the transfer of heat through electromagnetic waves.
• Convection involves the movement of molecules in a fluid, carrying heat from one place to another.

• Radiation does not require a medium to transfer heat and can occur through a vacuum.

• Examples of convection include boiling water in a pot and hot air rising...read more

Q1. Explain oops concept to me
Ans. 
OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
• OOPs focuses on creating objects that interact with each other to solve a problem.

• It involves concepts like inheritance, encapsulation, polymorphism, and abstraction.

• For example, a car object can have properties like color and speed, and methods like accelerate and brake.
