Document Summary
Energy, e = unit of force unit of distance = n m = joul or j. Forms of energy: (a) macroscopic: the macroscopic forms of energy are those a system possesses as a whole with respect to some outside reference frame. For example, molecular translational, rotational, vibrational kinetic energies. Internal energy: the sum of all the microscopic forms of energy is called the internal energy (u) of a system. Total energy: sum of all macroscopic and microscopic forms of energy. Pe other forms of energy (magnetic, chemical, etc. ) 2 other forms of energy (magnetic, chemical, etc. ) Energy transfer processes: energy transfer processes from a system to its surrounding or from surrounding to a system or between two systems, examples, Heat: heat is defined as the form of energy that is transferred between two systems (or a system and its surroundings) by virtue of a temperature difference.
