Um......your question is worded oddly, but the way an thermos is insulated is by having a vacuum between it's two flasks. The vacuum causes heat transfer to reduce greatly.
Thermos is a trade name for an insulated food and beverage container
The spelling is "thermos" (still a trademark name Thermos), a vacuum-insulated flask.

There are many brands of insulated tumblers. Thermos is popular for their products as are the Contigo brand. Both brands have various sizes and colors.
Stainless steel is a popular material for thermos flasks because it is durable, has good insulating properties, and is easy to clean. Vacuum-insulated stainless steel thermos flasks can keep liquids hot or cold for long periods of time.
Yes, you can store milk in a thermos flask, as long as the flask is clean and insulated to keep the milk at a safe temperature. It's best to use a vacuum-insulated thermos to maintain the milk's freshness and prevent bacterial growth. However, be sure to consume the milk within a few hours for optimal taste and safety. Always check the temperature before drinking to ensure it hasn't spoiled.
Actually i dont know ,i am here just like u, to find an answer of this question but thank me that i questioned this question firstlY.
Thermos
An insulated thermos containing hot coffee is a good example of an isolated system. The thermos prevents heat transfer with the surroundings, keeping the coffee hot for a longer period.
The Thermos vacuum bottle model no 2460S quart size was likely manufactured in the mid-20th century, around the 1950s-1970s. This model was produced by the Thermos division of King-Seeley Corporation, a prominent manufacturer of insulated food and beverage containers during that time period.
An insulated system is a physical system that does not exchange heat or matter with its surroundings. This can be achieved through materials or barriers that prevent energy transfer, effectively maintaining a constant internal state. Examples include thermos bottles or insulated walls, which help preserve temperature. In thermodynamics, insulated systems are important for analyzing energy transformations without external influences.
To keep food warm in a kids' Thermos, preheat the Thermos by filling it with boiling water for about 10 minutes, then empty it. Next, add the hot food, ensuring it's freshly cooked and steaming. Seal the Thermos tightly to maintain heat and store it in an insulated bag if needed. This method can keep food warm for several hours, making it suitable for lunchtime or snacks.
