The three laws of thermodynamics are fundamental principles that describe the behavior of energy and entropy in physical systems:

1. **Zeroth Law of Thermodynamics**:  
   *If two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.*  
   This law establishes the concept of temperature and justifies the use of thermometers.

2. **First Law of Thermodynamics** (Law of Energy Conservation):  
   *Energy cannot be created or destroyed in an isolated system; it can only change forms.*  
   Mathematically, this is often expressed as:  
   \[
   \Delta U = Q - W
   \]  
   where \(\Delta U\) is the change in internal energy of the system, \(Q\) is the heat added to the system, and \(W\) is the work done by the system.

3. **Second Law of Thermodynamics**:  
   *The total entropy of an isolated system can never decrease over time; it either increases or remains constant in ideal reversible processes.*  
   This law introduces the concept of irreversibility and explains why certain processes occur spontaneously in one direction (e.g., heat flows from hot to cold).

There is also a **Third Law of Thermodynamics**, which is sometimes included as the fourth in historical contexts but is now standardly recognized as the third:

4. **Third Law of Thermodynamics**:  
   *As the temperature of a system approaches absolute zero, the entropy of the system approaches a constant minimum value.*  
   In practical terms, it implies that absolute zero (0 K) cannot be reached in a finite number of steps.

So, while commonly referred to as “three laws,” modern physics includes **four**—with the Zeroth Law added later for logical completeness, even though it was formulated after the first three.

``` To read a JSON file in Python, you can use the built-injson` module. Here's the basic approach:

Basic Example

```python import json
