Question

How do the thermoflask prevent heat loss?​

Answer 1

Answer:

Yes, thermoflask is designed to prevent the contents of the flask from losing heat. The stopper, i.e. vacuum between double walls of thermoflask prevents heat transfer through convection. The glass walls are silver coated because it reduces emitted radiation when they are silver coated i.e. made shiny.
