Gay-Lussac's Law is a fundamental principle in thermodynamics, linking the pressure of an ideal gas to its temperature at a constant volume. This law is vital for predicting gas behavior under thermal stress and has applications in cooking, automotive maintenance, and chemical engineering. It's essential for safety in everyday devices and industrial processes, demonstrating the direct proportionality between gas pressure and temperature.
