Will the thermos cup be damaged by putting ice water in it?

The thermos cup is a kind of cup, if you put hot water in it, it will keep hot for a period of time, which is very necessary in winter, even if you take it out, you can drink hot water. But in fact, the thermos cup can not only put hot water, but also ice water, and it can also keep it cold. Because the insulation of the thermos cup is not only to keep warm, but also to keep cold. Let’s learn more about it together.

Will the thermos cup be damaged by putting ice water in it?
Putting ice water in the thermos cup will not break it. The so-called thermos bottle has the dual functions of heat preservation and cold preservation, and the heat preservation value is to maintain a constant temperature, so it is called a thermos bottle. This is not only a mug that can keep hot, but the mug can also hold cold water or even ice water.

The principle of vacuum bottles is to prevent multiple heat transfer paths. After the hot water is filled, the heat in the cup cannot be transferred to the outside of the cup, and the hot water cools down slowly. When filled with ice water, the heat from the outside of the cup is transferred to the inside of the cup. It is also blocked, and the ice water in the cup heats up slowly, so it has a heat preservation effect, which prevents the temperature from being constant or rising slowly.

But I would like to remind you that it is best not to fill the thermos with iced drinks, especially acidic drinks, such as soy milk, milk, coffee, etc.

Will the ice water in the thermos be kept cold?
The thermos cup can be filled with ice water, and the ice water can also be kept in a cold state in the cup, and the temperature of the ice water can be kept at 0 degrees or close to 0 degrees. But put in a piece of ice, and what comes out is half water and half ice.

The silver liner inside the thermos cup can reflect the radiation of hot water, the vacuum of the cup and the cup body can prevent the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection. On the contrary, if the ice water is stored in the cup, the cup can prevent the external heat from dissipating into the cup, and the ice water is not easy to get cold.
