Which of the following is incorrect?
heat capacity can be negative
heat capacity can be infinitely large
heat capacity can be zero
heat capacity can only have positive finite value
Total heat capacity -
For adiabatic process
dq = 0 then C = 0
For isothermal
dT=0 then C
If dq < 0 then C is negative
So, "heat capacity can only have a positive finite value" is incorrect.
