Discretionary calories are the calories available to a person to spend after theyâve already met their nutrient needs for a day.1.
Thermodynamics is the study of energy. First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.hermodynamics is the study of energy.

Any change in the internal energy of the system is equal to the difference between its initial and final values. E sys = E f-E i. The First Law Of Thermodynamics. The first law of thermodynamics can be captured in the following equation, which states that the energy of the universe is constant.he heat given off or absorbed when a reaction is run at constant volume is equal to the change in the internal energy of the system. E sys = qv. 2. The heat given off or absorbed when a reaction is run at constant pressure is equal to the change in the enthalpy of the system.
