How do the principles of convection conduction and radiation explain how the water in the saucepan gets hot?
Convection: Hot water at the bottom rises, displacing cooler water, which then heats up and rises, creating a circulation that evenly distributes heat in the saucepan. Conduction: Heat is transferred directly from the stove to the saucepan, warming the metal of the saucepan which then transfers heat to the water in contact with it. Radiation: Heat from the stove is emitted as electromagnetic waves, which are absorbed by the saucepan and water, causing the molecules to vibrate and raise the temperature.

How does the principles of convection conduction and radiation explain how water in a saucepan gets hot?
Conduction is the heat transfer between the saucepan and the water through direct contact, convection is the transfer of heat through the movement of the water molecules due to the temperature difference, and radiation is the heat transfer from the stove to the saucepan through electromagnetic waves. These principles work together to heat the water in the saucepan evenly.

Why it is not possible to produce steam in open vessel?
Steam is produced when water vapour condenses in air. If the air in a vessel is cold enough, steam can be produced in it, open or closed. Mostly, say in a saucepan, the air above the boiling water is heated in the process of boiling, so it is too hot for the water vapour to condense in the saucepan. However, if you pour some very hot water into a cold bath (for example) you may well notice clouds of steam forming above it.

When cooking in a saucepan with a lid on what is the water that accumulates on the inside of the lid?
The liquid in the pan gets hot, and creates water vapor. The lid, blanketed by the outside air, is cooler than the liquid in the pan, so the water condenses on the underside of the lid.
