Working of a thermos bottle
The operation of a thermos bottle is based on the basic principle of heat transfer. The heat will be passed between two bodies of varying temperatures until they reach the same temperature called thermal equilibrium. When you put a cup of hot tea in contact with ice, the temperature of a cup of tea will decrease, and the temperature of the ice will increase. The ice starts melting, and the tea comes at a lower temperature. It ends when they’re at the same temperature.
Heat can be transferred by three methods of conduction, convection, and radiation.
Heat transferred through direct contact
Heat transferred through the motion of matter
Heat transferred through electromagnetic waves
Thermos bottles operate on the basic idea of making a vacuum between the drinks and the surrounding area. The vacuum prevents heat transfer by conduction and convection. Thus, heat transfer is only possible through radiation. The outer and inner body of the thermo-steel bottle is separated by two layers of glass or stainless steel with a vacuum placed in between. So the drink is isolated from the room temperature and thus prevents the transfer of heat. Generally, the outer body is kept shiny so that the reflection further helps to retain heat.

Tips for using a thermos bottle
After you chose a thermos from 10 Best Thermos bottles in India 2020, follow the below steps to get better results.
Pre-condition the thermos bottle before use
Pre-conditioning the thermos bottle means matching the temperature of the bottle and the beverage. The simple physics behind this is the heat transfer between two materials of different temperatures. The higher the difference between the walls and the drink, the higher the heat transfer.
Before using the thermos bottle to store hot drinks, place a bowl of hot boiling water, and close the lid for 2 minutes. The inner walls of the thermo-steel bottle get hot because of the steam. This is a method that saves water. If you want to save time, fill hot boiling water till the brim. Use this water after 1 minute to wash other utensils. Put the hot drink in the thermosteel bottle and close the lid. With this method, a hot drink can be hot for a lot more time.
Before using the thermos bottle to store cold beverages, add 7-8 ice cubes. Stir the bottle so that ice touches every part of the inner body. Keep the ice cubes for 2 minutes to cool the body. Now, throw them away. Add the drinks and close the lid. This method keeps the cold drinks cooler for a longer time.
Do not fill the liquid upto the brim
Please leave a half-inch gap between the edge and the liquid The three methods of heat transfer are conduction, convection, and radiation. Thermos bottle walls are covered by a vacuum between inner and outer glass. The thermos bottle top, however, uses rubber, not a glass wall. When the liquid comes into contact with the top, it can transfer heat by convection. The above tip can help the liquid remain cool/hot for much longer.
Try to keep the thermos bottle filled
Buy a thermos bottle according to the requirement. Try to keep the bottle till half-inch below the brim. The more empty the bottle is, the more the air is accumulated in the container. More air contributes to heat transfer. If we are using a thermos bottle for an individual, we should buy a thermos bottle of 500 ml. We should buy a thermos bottle with large amounts only if you are buying it for our family. Seek to use all the bottle liquid at once, as leaving the bottle half-filled neutralizes the temperature.

Prevent thermos from physical damage
The thermosteel bottle has two layers of glass that block air from coming in, creating a vacuum. If the bottle drops from a height, it cracks the glass and lets the airflow in. The bottle can no longer retain heat and stop working as we want. We should prevent it from any kind of physical damage. Physical damage is not protected under any warranty. The only option left is to use it as a simple container.
Wash the thermos bottle carefully
Do not use abrasive liquids like acids during bottle washing. Don’t use rough scrub to clean your outer body. The external body is designed to reflect the heat coming. If you use a coarse scrub, this not only causes a scratch on the body but also affects the working. Doing so won’t yield expected results.
Do not treat the outer body under immense hot or cold temperatures
Treatment at tremendous temperature can harm glass walls used to keep the vacuum intact. Once the vacuum is lost, the bottle won’t do the same again.
Treating the outer body under extreme hot or cold conditions can ruin the bottle’s work.
The other disadvantage of doing this is that it will melt the rubber rim or the lid itself.
