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
