Answer to Question 1

Work can be completely changed into heat by the second law of thermodynamics. Heat engines with 100 efficiency are prohibited, but the prohibited part is changing heat into work. To understand this example, imagine dragging a box along the ground with a constant force. The work put into the system accelerates the box against the force of friction, but eventually friction slows the box to a complete stop. The friction basically turns the energy of the box into heat.

Answer to Question 2

Maxwell's work in unifying the equations for electricity and magnetism helped bring about many of the innovations dealing with electromagnetic radiation that make our lives easier on a daily basis. His work helped with the development of fiber optic communication that makes nearly instantaneous global connection possible
