A Flask
the answer is it gets it colder
Yes, both a thermos and a glass cup can help keep liquids hotter for longer periods of time compared to a regular open container. This is because they have better insulation properties, reducing heat transfer between the liquid and the surrounding environment.
A flask :)
Plastic generally does not keep liquid hotter than a foam container or glass container. Foam containers have better insulating properties, making them more effective at retaining heat. Glass containers also have higher thermal conductivity, which can help keep liquids hotter for longer periods compared to plastic.
styrofoam, but warning fammable and unsafe for the environment!
Igloo-type cooler.
yes
An insulated container or flask can help keep liquids either warm or cold by reducing heat transfer between the liquid and its surroundings. Additionally, ice packs or heating pads can be used to maintain the desired temperature for longer periods of time.
If you are using wood, metal, plastic, or a thermos it would have to be a thermos because inside of it there insulators. Insulators are used to keep whatever is inside the same without the stuff outside interfering. Why else do you think we drink hot coffee in a thermos.
substances cool as they lose heat energy, and get warmer as they gain heat energy. A thermos is an insulated container which opposes the movement of heat, thus hot liquids lose heat to the cooler outside more slowly and stay hotter for longer and cold liquids gain heat from the outside more slowly and stay colder for longer.
To ensure that cut fruit stays fresh for longer periods of time, store it in an airtight container in the refrigerator, use lemon juice to prevent browning, and avoid exposing it to air for extended periods.
To keep an ice bath cold for longer periods of time, you can add more ice, use a larger container to hold the ice bath, insulate the container with towels or blankets, and keep the ice bath in a cool place away from direct sunlight or heat sources.
