The diagram below shows a saucepan containing water placed on a hot plate.After some time the air at point x also becomes hot.


1/ State the process by which heat is being transferred from hot plate to the point X?
Heat is transferred from the hot plate to the stainless steel saucepan by conduction and then convection currents are set up so that the milk is heated up. After which heat reaches X through radiation and convection
2/ The side pf the saucepan are often polished. How does this reduce heat loss?
The sides of the saucepan are often polished, do that the heat lost through radiation is low. Shiny surfaces are poor radiations of heat.
