Question

explain how conduction Convection and radiation are minimised in a thermos flask.
​

Answer 1

1. the inner covering of a thermoflask is coated with an insulator of heat hence conduction minimise
2. the outer covering is a lusturous metal which radiates the heat of sun back

Answer 2

$\huge\red{ꫝꫀꪶꪶꪮ}$

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