If released, the chemical potential energy will cause the coal 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? A. burn the coal B. drop the coal from a great height C. roll the coal down a hill D. submerge the coal in water

A. burn the coal

Explanation:

Burning the coal is only the way to convert the stored chemical energy of the coal into the the kinetic energy of its molecules that can then be transferred to the nearby objects in the form of heat by the various modes of heat transfer such as conduction, convection or radiation.

Conduction is the contact method of heat transfer in which the adjacent atom transfers the vibration kinetic energy.

Convection is the bulk mode of heat transfer in which the bulk mass of molecules moves near and far to the heat source.

Radiation is the distant mode of heat transfer in the form of electromagnetic waves.

probably not if net force is zero

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
