... for the 1st question... it is b or Heat Q = mass x specific heat x  change in Temperature...

can we consider potential energy as work?

anonymous · Answer

yes we can, although PE usually consider vertical displacement such as $$PE=mgh$$where the "mg" part refers to the Weight (equivalent to a Force) and height h is the vertical displacement where a similar Work is being made... Work is defined force times distance... can be applied in any direction... in most cases... $$\Delta W=-mg~\Delta h$$
