1. When analyzing the energy transfer within a propulsion system, specific heat can be used to determine the change in enthalpy (ΔH) of the working fluid as it goes through various processes. The change in enthalpy is related to the heat input or output and can be expressed as:$\Delta H=m\ast Cp\ast \Delta T$

   Where:

   • ΔH is the change in enthalpy (in joules or calories).
   • m is the mass of the working fluid (in kilograms or grams).
   • Cp is the specific heat at constant pressure (in J/kg°C or cal/g°C).
   • ΔT is the temperature change (in degrees Celsius).

   This equation is important for understanding the energy transfer in propulsion processes.

Specific heat is a fundamental property of the working fluid that influences the performance and efficiency of propulsion systems, and it is often used in conjunction with other thermodynamic properties and equations to analyze and design these systems.
