Internal energy is the energy needed to bring a system from standard to current state. Excludes kinetic and potential energy due to system motion and external fields. Includes thermal energy of constituent particles relative to system motion. Cannot be measured absolutely, only changes in internal energy
Energy is a conserved quantity that cannot be created or destroyed. SI unit of energy is the joule (J). Energy can be transferred between forms through work or heat
Enthalpy of vaporization measures energy needed to convert liquid to gas at constant pressure. Formula: Hvap = q/n, where q is heat absorbed and n is moles. Water's boiling point enthalpy is approximately 40.7 kJ/mol at 100°C
Total energy remains constant in any process. Energy can change form but total remains same. Conservation equation includes all forms except mechanical energy
Students will learn to apply First Law to aerospace power systems. Course focuses on understanding heat, work, and energy transformations. Students will learn to explain various heat engines and their operation
