Specific Heat at Constant Pressure in Fluid Pressure and Its Measurement Formulas

No, the Specific Heat at Constant Pressure, measured in Specific Heat Capacity cannot be negative.

Specific Heat at Constant Pressure is usually measured using the Joule per Kilogram per Celcius[J/kg*°C] for Specific Heat Capacity. Joule per Kilogram per K[J/kg*°C], Kilojoule per Kilogram per K[J/kg*°C], Kilojoule per Kilogram per Celcius[J/kg*°C] are the few other units in which Specific Heat at Constant Pressure can be measured.
