A chunk of coal has a substantial amount of chemical potential energy. if released the chemical potential energy will cause the cool atoms and molecules to vibrate violently, and this internal kinetic energy can be transferred to other nearby objects. which of these is the best way to transform this chemical potential energy into internal kinetic energy?

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab. 

Tell me the answer choices and i would be able to answer. : )

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
