Thermal Expansion
Thermal expansion is a fundamental concept in physics and engineering, describing the tendency of matter to change in volume in response to changes in temperature. As substances absorb heat, their particles gain kinetic energy, leading to increased movement and spacing. This phenomenon manifests in various materials, from solids and liquids to gases, and plays a crucial role in numerous applications, including construction, manufacturing, and everyday devices. Understanding thermal expansion is essential for designing structures and systems that can withstand temperature fluctuations and for ensuring the reliability and longevity of engineering components.
