A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?

• Energy was destroyed during certain steps in the experiment.

• The steps in the experiment required more energy than was available

• The experiments produced energy that was then used up at a faster rate

• Some energy was transformed into unwanted heat or sound that was not detected.
