THERMOS Meaning and
Definition
-
A thermos is a portable container designed to keep liquids hot or cold for extended periods of time. It consists of a double-walled vessel with a vacuum layer in between the walls, which helps to insulate the contents and maintain their temperature.
The outer layer of a thermos is generally made of metal or plastic, while the inner layer is usually made of glass or stainless steel. This inner layer is where the liquid is stored and its temperature is preserved. The vacuum insulation prevents heat transfer through conduction, convection, and radiation, making it highly effective at preserving the temperature of the liquid inside.
Thermoses are commonly used to keep beverages such as tea, coffee, soup, or cold drinks at the desired temperature. They are particularly useful for people who are on the go, as they allow them to enjoy a hot or cold drink throughout the day without the need for reheating or refrigeration.
Furthermore, thermoses are often equipped with secure lids or stoppers to prevent spills and leakage, providing convenience and peace of mind when transporting liquids. They come in various sizes and shapes to accommodate different needs.
Overall, a thermos is a practical and reliable solution to preserve the temperature of beverages while on the move, offering convenience and ensuring refreshing drinks for longer periods.
