One liter of water is heated using a pot until it boils and produces steam.
When the water boils, heat transfer occurs through convection
After boiling, the water will produce a significant amount of steam, and this is where heat transfer occurs
through convection
When the pot becomes hot, heat transfer occurs through radiation
In the process of boiling water, there is no heat transfer at all
