Thermodynamics: It’s a branch of physics that delves into the relationship between heat and other forms of energy, including work, mechanical, radiation, and chemical energy.

- Systems: A certain amount of matter or a region in space upon which attention is concentrated during analysis.
- Properties: Any observed aspect or characteristic of a system, such as pressure, temperature, density, and others.
- Equilibrium: A state when all forces are balanced, with no changes occurring over time.

- \(0^{th}\) Law: If two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other.
- \(1^{st}\) Law: The law of conservation of energy - energy cannot be created or destroyed, only transferred or transformed.
- \(2^{nd}\) Law: Energy systems have a natural direction of progression; Heat will always flow spontaneously from hot to cool bodies.

Heat: It’s a form of energy transfer that takes place due to a temperature difference.

Work: Work is any energy transfer that isn't heat. In simpler terms, it's the energy transferred to an entity by applying force along a displacement.

First Law of Thermodynamics: This crucial law essentially states that energy cannot be created or destroyed. It's always conserved, only changing from one form to another.

Work (W) | Energy transfer without change in temperature |

Energy (E) | Capacity to do work |

- \(\Delta U\) represents the change in internal energy of the system,
- \(Q\) stands for the heat transferred into the system, and
- \(W\) signifies the work done by the system.

Consider a steam engine; the heat (Q) from burning coal enters the system, changing the water into steam and increasing its internal energy (U). This then forces the pistons to move, performing work (W) on the wheels and surroundings. However, the total energy (coal heat + internal energy of water) is conserved before and after the process, demonstrating the first law of thermodynamics.

**First Law of Thermodynamics:** Also known as the law of energy conservation, it establishes the concept of energy as a quantity that is conserved in any process.

**Second Law of Thermodynamics:** It introduces the concept of entropy and establishes the direction and feasibility of a process.

**Third Law of Thermodynamics:** It offers a fundamental reference point for the measurement of entropy.

**Energy Balance:** It involves the calculation of energy inflow, outflow, and storage in a system.

**Entropy and Enthalpy:** Entropy represents the degree of disorder or randomness in a system while enthalpy is a measure of the total energy of a thermodynamic system.

**Ideal Gas Law:** The property relationship for an ideal gas represented by \(PV=nRT\).

Here is a step-by-step guide to problem-solving in Engineering Thermodynamics:

**Step 1: Analyze the Problem**: Read the given problem thoroughly and identify all given data. What are you asked to find? What system is involved - closed, open, or isolated? Is any information about the system given? Is the process adiabatic, isothermal, isobaric, or isochoric?**Step 2: Identify the Appropriate Principles**: After assessing the given information, identify the relevant thermodynamic principles needed to solve the problem. This could include any of the laws of thermodynamics, energy balance equations, or property relations such as the ideal gas law.**Step 3: Write Down the Equations**: Once you've identified the principles, write down the associated equations. It’s crucial to ensure that all terms in the equation are defined and understood.**Step 4: Solve the Equations**: Enter the given values into the equations and solve them. If you need to find more than one unknown, you might need to set up a system of equations and solve them simultaneously.**Step 5: Check the Reasonableness of the Answer**: Always check if your solution makes sense physically and aligns with the basic principles of thermodynamics.

Fundamentals of Engineering Thermodynamics is a subfield of engineering that provides an understanding of energy, its utilisation, and its transformation. It involves studying heat, work, systems and processes, exploring laws of thermodynamics, and analysing thermodynamic relations and cycles.

The fundamental concepts of thermodynamics include the laws of thermodynamics (zeroth, first, second and third), system and control volume, state and equilibrium, temperature and zeroth law, pressure, energy and the first law, entropy and the second law, and properties and state of a substance.

The principle of engineering thermodynamics is understanding and applying the laws of energy transfer, which involves concepts of heat and work, to analyse and devise systems that convert energy from one form to another, often with the purpose of doing useful work.

The three basic principles of thermodynamics are: the Zeroth Law, which states that if two systems are in thermal equilibrium with a third, they are also in equilibrium with each other; the First Law, or the conservation of energy; and the Second Law, which states that entropy of isolated systems never decreases.

The difficulty of thermodynamics for engineers greatly depends on one's mathematical aptitude and understanding of basic physics. It involves complex concepts and requires abstract thinking and mathematical calculations. However, with diligent study and practice, it's manageable.
