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

Yes, the Specific Heat at Constant Volume, measured in Specific Heat Capacity can be negative.

Specific Heat at Constant Volume 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 Volume can be measured.
