critical exponent

[′krid·ə·kəl ik′spō·nənt]
(thermodynamics)
A parameter n that characterizes the temperature dependence of a thermodynamic property of a substance near its critical point; the temperature dependence has the form | T-Tc | n , where T is the temperature and Tc is the critical temperature.
