The amount of gas used for boiling water at home is proportional to the volume of water being boiled, right? It has nothing to do with the degree to which the gas stove valve is opened, does it?
The opening degree may affect thermal efficiency, but generally no one pays too much attention to this. I usually use electric heating.
To some extent, it is related, and sometimes the relationship is quite strong. You can try boiling water with a lamp kept on; if the kettle is large, it’s possible that even with gas supply, the water won’t boil, as the heat lost by the kettle is roughly equal to the heat released by the burning lamp.
Heat loss should be taken into account. There is also a speed at which driving is more fuel-efficient; it’s not the case that the faster you drive, the more fuel-efficient it is.
This is a mathematical problem, and an optimal solution should be possible to find. Under normal circumstances, an open flame causes some heat loss, and hot water also loses some of its heat
It is related to the opening degree; it cannot be set too large nor too small. If it is set too large, the flame becomes longer, the temperature rises, and heat loss through radiation increases. If it is set too small, the input is not sufficient to meet the demands
