When you consume (eat) 105 J of chemical energy stored in food, how much of it has been transformed into kinetic energy that allows you to do daily activities?
1 answer
The efficiency of the human body in converting chemical energy into kinetic energy is estimated to be around 20-25%. Therefore, if you consume 105 J of chemical energy stored in food, only 21-26 J of it will be transformed into kinetic energy that allows you to do daily activities.
