Homonym: 열 (Heat)
"열" (yeol) is a Korean word that translates to "heat" or "temperature" in English. It refers to the energy that causes the sensation of warmth and is a fundamental concept in physics. Heat can be transferred between objects through conduction, convection, and radiation, affecting their temperature and state.
In everyday life, "열" is commonly associated with cooking, weather, and comfort. For example, when cooking food, the application of heat changes its texture and flavor. Additionally, understanding "열" is essential for managing indoor climates, such as using 에어컨 (air conditioning) or 난방 (heating) systems to maintain a comfortable environment.
