Draw a vacuum flask and label it fully. State the functions of the following parts of the flask:
a) The cork cover
b) The silvered surfaces
c) The vacuum inside the double wall.

Asked by isaactenin05

Answer (2)

A vacuum flask contains a cork cover to seal in heat, silvered surfaces to reflect heat radiation, and a vacuum layer to minimize heat transfer. These features work together to maintain the temperature of its contents. This design allows the flask to keep liquids hot or cold for extended periods. ;

A vacuum flask consists of a cork cover that seals heat in, silvered surfaces that reflect heat radiation, and a vacuum between its walls that minimizes heat transfer. These features work together to maintain the temperature of the liquid inside. This design allows the flask to keep contents hot or cold for an extended time.
