energy is first gained and eventually lost
energy is never gained, but it can be lost
energy can be gained, but not lost
energy is never gained or lost it just changes forms
burning violates this law because energy is lost as heat
the energy held in the chemical bonds of paper is changed into the energy of heat
it violated the law because there was no ice for that burn
the energy held in the chemical bonds of paper is greater than that lost as heat
the energy held in the chemical bonds of paper is less than that lost as heat
