A device in which heat loss due to conduction, convection and radiation is minimized is :
Open in App
Solution
The correct option is B thermos flask
Thermos flask is the device in which heat loss due to conduction, convection and radiation is minimized.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 glass walls stops heat transfer by conduction. The case surrounding the flask provides additional insulation.
