How do you keep drinks hot?

Why does liquid remain hot or cold for a long time inside a thermos flask?

A thermos flask has a double-walled design with a vacuum layer in between, which minimizes heat transfer by conduction and convection. This helps prevent heat loss or gain from the liquid inside, keeping it hot or cold for a longer time. Additionally, the reflective lining inside the flask reduces heat transfer by radiation.

Why hot water kept in a thermoflask remain hot for a considerable period of time?

A thermos flask is designed with double-walled insulation to minimize heat transfer. The vacuum between the walls prevents heat from escaping through conduction or convection. Additionally, the reflective surface on the inner wall reduces heat loss through radiation. This combination of insulation techniques helps hot water stay hot for a long time in a thermos flask.
