Question

Discuss the functions of a thermo flask in terms of conduction, convection, and radiation. what improvements would you add to a modern day thermo flask?

Answer 1

Oh man. Silver coating to dampen radiating heat is great but that, of course does not tell you the temperature of the fluid inside; I would definitely add a small thermostat somewhere around the exterior. that's the only improvement I would suggest, as a standard for all.
