The vacuum and silvered wall surfaces of a vacuum flask walls are respectively
- minimize conduction and convection and prevent radiation
-
prevent conduction and convection and minimize radiation
- prevent conduction and minimize convection and radiation
- minimize convection and prevent conduction and radiation
The correct answer is: B
Explanation
Vacuum: It prevents conduction and convection because there are no air molecules to transfer heat.
Silvered Walls: They minimize radiation by reflecting thermal radiation back.
