2. maria ... (mare, maris N - 3rd declension, accusative plural) ... since it is neuter it is spelled the same as the nominative (very confusing at times, no?).
When you burn a wood, you are making heat. And heat can transfer from one material to another. Also, you should know that heat is a source of energy. So heat transfers from burning wood to the sausages that you are cooking. The answer is: Heat :)))) I hope this is helpful have a nice day
