Question

Explain why a vacuum flask can keep drinks cold as well as hot and suggest why the vacuum flask is commonly called the thermos flask?​

Answer 1

Answer:

Here's your answer.

Explanation:

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.
