In aircraft design and engineering, “heat energy” (Q) represents the energy transferred between a system and its surroundings as a result of a temperature difference. Heat energy is a form of energy associated with the random motion of molecules within a substance.
The formula for calculating heat energy can be defined as:
- Heat Energy (Q) is the amount of heat transferred, typically measured in joules (J) or other energy units.
- Mass (m) is the mass of the substance involved in the heat transfer, typically measured in kilograms (kg) or other mass units.
- Specific Heat Capacity (c) is the specific heat capacity of the substance, which represents the amount of heat energy required to raise the temperature of a unit mass of the substance by one degree Celsius (or one Kelvin). It is typically measured in joules per kilogram per degree Celsius (J/(kg·°C)) or other specific heat capacity units.
- Temperature Change (ΔT) is the change in temperature of the substance as a result of the heat transfer, typically measured in degrees Celsius (°C) or Kelvin (K).
