Which of the following best defines the First Law of Thermodynamics? a. The total kinetic energy of an object must be equal to the initial potential energy of that object and system

b. In order to change the internal energy of a system, you must either apply heat to the system, take heat out of the system, have work done on the system, or have the system do work

c. The total net force acting on an object is equal to the multiple of the mass of the object and the acceleration of that object

d. The total amount of disorder in a system can never decrease unless excess energy in the form of work is done on the system
