2.the inside substances of samosa have more specific heat so it retains hotness for a long time.... therefore appears to be cool outside but it is hot inside.
3.temperature : as the temperature increases, the rate of evaporation also increases
surface area : as the surface area increasea, the rate of evaporation also increases
4.heat : heat describes the transfer of thermal energy between molecules within a system and is measured in joules.
temperature : temperature describes the average kinetic energy of molecules within a material or system and is measured in celsius.
