The intensive properties c v and c p are defined for pure, simple compressible substances as partial derivatives of the internal energy u(T, v) and enthalpy h(T, p) , respectively:
WebThe question asks for an amount of heat, so the answer should be an amount of energy and have units of Joules. Step 4: Predict the approximate size of your answer. Water has a very high heat capacity, about 4 J/gºC. Therefore the answer should be about 4 • … Web(Note that this is similar to determining the intensive property specific heat from the extensive property heat capacity, as seen previously.)
