Can specific heat of a gas be negative?

Answer:

                Yes; negative specific heat will imply that with rise in temperature \[\text{( }\!\!\Delta\!\!\text{  }\!\!\Tau\!\!\text{  is + ve)}\] heat will be released\[\text{(Q is - ve)}\]. This actually happens in case of saturated vapour i.e., specific heat of saturated vapour is negative.
