"<span>The process by which your body converts food into energy", sounds more accurate.
"</span><span>The amount of potential energy contained in food", is basically a long way of saying - Calories.
So, I would go with the one that talks about the process of converting food to energy.</span>
Answer:
The maximum no. of electrons- 
Solution:
As per the question:
Maximum rate of transfer of charge, I = 1.0 C/s
Time, t = 1.0 h = 3600 s
Rate of transfer of charge is current, I
Also,
Q = ne
where
n = no. of electrons
Q = charge in coulomb
I = current
Thus
Q = It
Thus the charge flow in 1. 0 h:
Maximum number of electrons, n is given by:
where
e = charge on an electron = 
Thus
Answer:
energy cannot be created or destroyed
Explanation:
Energy can't be created nor destroyed; rather, it transforms from one form to another.
The first law of thermodynamics is the law of conservation of energy. It states that energy is always conserved. ... To keep a machine moving, the energy applied should stay with the machine without any losses. Because of this fact alone, it is impossible to build perpetual motion machines.
The law of conservation of energy<span> states that the total </span>energy<span> of an </span>isolated system<span> remains constant. </span><span>Energy can neither be created nor destroyed; rather, it transforms from one form to another. For instance, </span>chemical energy<span> can be </span>converted<span> to </span>kinetic energy<span> in the explosion of a stick of </span>dynamite<span>.</span>
