Problem 9: What type of motion is termed a free vibration? natural, undamped (B natural, damped O forced, undamped D forced, damped Correct answer is marked, Please give detailed explanation on how to arrive to the answer
Whenever energy is transformed, there is always an increases in the free energy of the system. Free energy of the universe. Entropy of the system. Entropy of the universe enthalpy of the universe. Reactants capable of interacting to form products in a chemical reaction must first overcome a thermodynamic barrier known as the reaction's entropy activation energy endothermic level equilibrium point. Free-energy content
