explain why a vacuum flask can keep drinks cold as well as hot.
Answers
Answer:
This happens because Vaccum Flash acts as an insulator which prevents radiation of heat as well as room heat acting on liquid inside the flask
A vacuum flask keeps the contents in it at the same temperature and blocks the outer temperature from entering it.
Explanation:
A vacuum flask is considered as the insulating storage that keeps the contents in it as the same temperature. It is mainly used for domestic usage and also for various industrial purposes. Generally the heat transfer with the help of three main things. they are,
- Conduction
- Convection and
- Radiation
The conduction is stopped with the glass material, the two containers in the vacuum flask stop the Convection and the shiny silver that is presented on the surface stops the radiation. Thus the structure of the vacuum flask stops the possibilities of heat or cold to enter in it.
