My Question was not well received in physics.stackexchange.com and I get a simple answer when I want to know the theory inside this question. I want to cook more efficient wasting less ( gas or electricty ) so my though is this when I boil the water cooking cassava the heat is 100° costant then the flame can be reduce for not waste energy, and the water still will be 100° otherwise if I am cooking at the flame is at the maxiximum temperature this food will be cooked faster?. so we have 2 scenarios:
Flame Low = food ready in 30 minutes
Flame High = food ready in 10 minutes
Are this escenarios related like work and energy theorem?(e.g. if i reduce the flame to medium will be ready in 20 minutes ) I want to know the performance and the waste of energy in each scenario, which is better for save gas?.
I take thermodynamics in my university but only law 0 and 1. and not too much of the 2nd law that is related to engineering. I know some basics of chemist process like matter&energy balance
This question is more for a professional of industrial process or chemical engineering so that's why I am posting here.
