because conduction,convection and radiation keep the flask thermal because of what they do
A thermos keeps hot drinks hot and cold drinks cold by using a vacuum layer between two walls of the container. This vacuum layer prevents heat transfer by conduction, convection, and radiation. The result is that hot drinks stay hot because heat loss is minimized, and cold drinks stay cold because heat gain is minimized.
To keep drinks hot, you can use an insulated thermos or travel mug that is designed to maintain heat retention. Make sure to preheat the container with hot water before filling it with your drink. Avoid leaving the lid off for too long, as this can cause heat to escape.
Vacuum flasks are named so because they have a double-wall design with a vacuum-sealed space between the walls. This vacuum insulation helps to minimize heat transfer by conduction or convection, keeping hot liquids hot and cold liquids cold for an extended period of time.
A thermos uses a vacuum-insulated layer between two walls of the container to minimize heat transfer through conduction, convection, and radiation. This helps to maintain the temperature of the drink by preventing heat loss to the surrounding environment. The airtight seal also helps to keep hot drinks hot for an extended period of time.
Yes, thermos flasks are designed to keep liquids cold by insulating them from the surrounding temperature. They typically have a vacuum-sealed layer that prevents heat transfer, helping to maintain the cold temperature of the liquid inside.
by inhibiting heat conduction
People can put alcoholic liquor drinks and wine in plastic flasks. You can also put water in plastic flasks as a drinkable liquid and carry them with you when you need it.
it can what is wired
A flask. It also keeps drinks hot.
styrofoam
Via insulation !!! There is an insulating air space between the liquid and the outside.
Styrofoam cups will keep a hot drink warmer for a long time. Insulated cups will also keep your drink warmer longer.
Put them in a thermos :D

Anorexics believe that it burns calories to drink hot or cold drinks because your body has to work to keep your body temp. at the normal range.
if its hot outside
To keep drinks hot, you can use an insulated thermos or travel mug that is designed to maintain heat retention. Make sure to preheat the container with hot water before filling it with your drink. Avoid leaving the lid off for too long, as this can cause heat to escape.
