+# Charles' Law Calculator
+
+## Overview
+
+This project is a web-based calculator that implements **Charles' Law**:
+
+\[(V_1 / T_1) = (V_2 / T_2)\]
+
+It allows users to calculate:
+
+- Final Volume \( V_2 \)
+- Final Temperature \( T_2 \)
+
+The calculator dynamically updates based on user inputs and provides instant results.
+
+## Features
+
+- **Dynamic Formula Display**: The formula for Charles' Law is displayed on the website for reference.
+- **Real-Time Results**: Automatically calculates the missing value when valid inputs are provided.
+- **Responsive Design**: The calculator works seamlessly across devices.
+- **Error Handling**: Guides the user with error messages for invalid or incomplete inputs.
+
+## Project Structure
+
+```
+charles-law-calculator/
+├── index.html       # HTML structure of the calculator
+├── style.css        # Styling for the calculator
+├── script.js        # JavaScript functionality for calculations
+├── README.md        # Project documentation
+└── assets/
+    └── background.jpg  # Background image for the calculator
+```
+
+## Setup and Usage
+
+### 1. Clone the Repository
+
+```bash
+git clone <repository-url>
+```
+
+### 2. Navigate to the Project Directory
+
+```bash
+cd charles-law-calculator
+```
+
+### 3. Open the Application
+
+Open `index.html` in any modern web browser to use the calculator.
+
+## How to Use
+
+1. Enter known values for \( V_1 \), \( T_1 \), and one of \( V_2 \) or \( T_2 \).
+2. Click the "Calculate" button to get the result.
+3. The missing value will be calculated using the formula:
+   \[(V_1 / T_1) = (V_2 / T_2)\]
+4. Clear inputs or refresh the page to reset the calculator.
+
+## Example Calculations
+
+### Case 1: Calculate Final Volume (\( V_2 \))
+
+- **Input**:
+  - Initial Volume (\( V_1 \)): `2 L`
+  - Initial Temperature (\( T_1 \)): `300 K`
+  - Final Temperature (\( T_2 \)): `450 K`
+- **Output**:
+  - \( V_2 = (2 × 450) / 300 = 3 L\)
+
+### Case 2: Calculate Final Temperature (\( T_2 \))
+
+- **Input**:
+  - Initial Volume (\( V_1 \)): `2 L`
+  - Initial Temperature (\( T_1 \)): `300 K`
+  - Final Volume (\( V_2 \)): `4 L`
+- **Output**:
+  - \( T_2 = (4 × 300) / 2 = 600 K\)
+
+## Technologies Used
+
+- **HTML**: For the calculator structure.
+- **CSS**: For styling and responsive design.
+- **JavaScript**: For implementing Charles' Law functionality.
