Overview

Have you ever heard of a perpetual motion machine? More to the point, have you ever heard of why perpetual motion machines are impossible? In this video, Dr. Shini discusses the first law of thermodynamics.

    SC15.PHYS.7

    Plan and carry out investigations to provide evidence that the first and second laws of thermodynamics relate work and heat transfers to the change in internal energy of a system with limits on the ability to do useful work (e.g., heat engine transforming heat at high temperature into mechanical energy and low-temperature waste heat, refrigerator absorbing heat from the cold reservoir and giving off heat to the hot reservoir with work being done).
