Thermodynamics - ANSWER-The study of heat and transformation into mechanical energy 1st Law of Thermodynamics - ANSWER-States that whenever heat is added to a system, it transforms to an equal amount of some other form of energy Internal energy - ANSWER-The total microscopic energy of an object, which includes its atomic and molecular translational and rotational kinetic energies, vibrational energy, and the energy stored in molecular bonds Adiabatic process - ANSWER-When a gas is compr...

What is Heat Transfer? - ANSWER-Heat Transfer is the transfer of thermal energy due to temperature difference Difference between thermodynamics and heat transfer - ANSWER-Thermodynamics deals with equilibrium state and changes from one equilibrium state to another. Heat transfer deals with systems that lack equilibrium. In other words, thermo deals with amount of thermal energy transfer, while heat transfer seats with the rate of energy transfer. 1st Law of Thermodynamics - ANSWER-The rate...
