'the process of energy being transfered, or lost, to the surroundings'- if this is the definition, what is the key word? A) transfer B) dissipation C) emitted

B

Explanation:

for A, transfer means energy change, from one form to another but remains unchanged.

But if we see, for energy lost to surroundings may be changed l.

For B , Dissipation is the process by which energy is done against dissipative forces, eg air resistance, viscosity.

For C, Not that every energy is dissipated, like kinetic and potential energy. But some forms of energy are emitted like heat energy.

the body's situation won't change the forces are equal opposit and on the same body

scientific laws are the result of testing theories and proving them to be facts.
