Problem
A vacuum flask is constructed with two glass walls separated by a near-vacuum and the inside surfaces are silvered. For thermal energy transfer across the evacuated gap, rank the mechanisms from greatest to least importance under steady conditions.
(a) Radiation > Convection > Conduction
(b) Radiation > Conduction > Convection
(c) Conduction > Radiation > Convection
(d) Convection > Radiation > Conduction
