Homonym: Burn (Injury)
"Burn" refers to the process of combustion, where a substance reacts with oxygen to produce heat and light. This reaction can occur in various materials, such as wood, gasoline, or paper. The result is often flames and smoke, which are visible signs of the burning process.
In a medical context, a burn is an injury to the skin or other tissues caused by heat, chemicals, electricity, or radiation. Burns are classified by their severity: first-degree burns affect only the outer layer of skin, while second-degree and third-degree burns penetrate deeper layers, potentially causing more serious damage.
