Problem

A vacuum flask is designed with (i) a double-walled glass container having vacuum between the walls, (ii) silvered inner surfaces, and (iii) a cork stopper at the mouth. Which option correctly matches each feature with the mode of heat loss it primarily reduces? (Order: feature (i) / feature (ii) / feature (iii)) (a) Convection / Radiation / Conduction\text{Convection}\,/\,\text{Radiation}\,/\,\text{Conduction} (b) Radiation / Conduction / Convection\text{Radiation}\,/\,\text{Conduction}\,/\,\text{Convection} (c) Conduction / Radiation / Convection\text{Conduction}\,/\,\text{Radiation}\,/\,\text{Convection} (d) Conduction / Convection / Radiation\text{Conduction}\,/\,\text{Convection}\,/\,\text{Radiation}
