Question

what is the function of silver lining in a vacuum flask​

Answer 1

$\huge\blue{\mid{\underline {\overline{\tt ❥Ꭺɴꮪꮃꭼꭱ♡}}\mid}}$

The silver coating on the inner bottle prevents heat transfer by radiation, and the vacuum between its double wall prevents heat moving by convection. The thinness of the glass walls stops heat entering or leaving the flask by conduction. The case surrounding the flask provides additional insulation.
