I just read a paper containing this term, "negative specific heat". I have only come across specific heat which is positive not a negative one. How is a negative specific heat be defined or possible?

That is not correct, the temperature is not proprtional to the kinetic energy. Rather, it should be determined from the statistical sum, which considered energy states (not only kinetic energy values).[tex]K \propto T[/tex]

Negative specific heat refers to a phenomenon where the temperature of a substance increases when the surrounding pressure decreases, and vice versa. This is in contrast to the traditional understanding of specific heat, which states that the temperature of a substance increases when heat is added and decreases when heat is removed.
Yes, negative specific heat has been observed in certain substances, such as water, during experiments where the pressure is reduced to extremely low levels. However, it is not a common occurrence and is not applicable to most substances.
The existence of negative specific heat challenges our understanding of thermodynamics and has implications for various fields of science, such as astrophysics and materials science. It also has potential practical applications, such as in the development of new cooling technologies.
Negative specific heat is a result of the complex interactions between particles in a substance. When the pressure is reduced, these interactions become more dominant and lead to an increase in temperature. However, the exact mechanisms behind this phenomenon are still not fully understood.
At this time, negative specific heat is not a viable source of energy production. While it has potential applications in cooling technologies, the energy required to create the extreme conditions needed for negative specific heat to occur far outweighs any potential benefits.
