ksülitool

Külm tool, often referred to as a "cold chair" in English, is a term that has gained some traction in discussions about everyday objects and their potential impact. The concept generally pertains to a seating surface that, due to its material or exposure to cooler temperatures, feels noticeably cold to the touch. This sensation can be more pronounced in certain environments or with specific types of furniture.

The materials commonly associated with külm tool include metal, stone, or certain plastics that do not retain heat well. In contrast, materials like wood, fabric, or upholstered surfaces tend to offer a warmer feel. The ambient temperature of a room also plays a significant role in how cold a chair might feel. For instance, a metal chair left in a room without heating during winter will likely be perceived as much colder than the same chair in a warm summer environment.

While not a formally recognized scientific term, "külm tool" is often used in informal contexts to describe this common tactile experience. It can be a minor point of discomfort or simply an observation about the properties of an object. Discussions around this topic might touch upon the selection of furniture for different climates or preferences for indoor comfort. The perceived coldness is a direct result of thermal conductivity and heat transfer between the body and the chair's surface.
