The yield of ethanol is proportional to the yeast cell growth(Cx). The efficiency of post-fermentation process is 80%. In the flow rate of 50L/hr, how long will be needed to produce 1000kg of ethanol

the right answer is c i just did the question.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
