The first law of thermodynamics seems to conflict with what we know about ourselves. For example, after strenuous exercise we run out of “energy.” We must eat to replenish our energy stores. Where has that energy gone? What form has it taken?
What will be an ideal response?
Muscular contraction requires energy in the form of ATP, this use of energy converts ATP to heat (another form of energy). Energy is not lost, it is just converted into a different form.
