A Control Point or "CP" is any step in the flow of food where a physical, chemical or biological hazard can be controlled. Where as A Critical Control Point or "CCP" is the last step where you can intervene to prevent, eliminate or reduce a hazard to an acceptable limit.

what is the difference between a 'traditional' and a 'personal' CV
No, this relation is ONLY for ideal gases. The difference between Cp and Cv can be written more generally as T*(dP/dT)v*(dV/dT)p, where the lower case v and p represent the derivatives taken at constant volume and pressure, respectively. If you take these two derivatives using the ideal gas law (PV=nRT), then the result simplifies to Cp-Cv=R. However, solids and liquids do not follow the ideal gas law, and the difference between Cp and Cv is much smaller... negligible in many cases. For solids, Cp-Cv can be calculated using the isobaric expansivity, isothermal compressibility, and density of the material.

The equation Cp - Cv = R is derived from the first law of thermodynamics applied to an ideal gas process. It relates the specific heat capacities at constant pressure (Cp) and constant volume (Cv) of an ideal gas to the universal gas constant (R). This relationship is based on the assumption that the internal energy of an ideal gas depends only on its temperature.

The general gas equation, PV = nRT, is used in the proof of the specific heat capacities relationship (Cp - Cv = R) because it helps relate the pressure, volume, and temperature of a gas to its moles and universal gas constant, allowing for the derivation of Cp and Cv in terms of these properties. This relationship is then utilized to show that the difference between the specific heat capacities at constant pressure and constant volume is equal to the universal gas constant.
v cv
The specific heat capacity (cp) of a substance measures the amount of heat needed to raise the temperature of a unit mass of the substance by 1 degree Celsius, while the molar heat capacity (cv) measures the heat needed to raise the temperature of one mole of the substance by 1 degree Celsius. The relationship between cp and cv is given by the equation cp cv R, where R is the gas constant. The number of degrees of freedom (nr) in a system is related to the molar heat capacity through the equation cv (nr/2)R. This means that the molar heat capacity is directly proportional to the number of degrees of freedom in the system.
Because Cp has two functions:- 1-To change the internal energy dU. 2-To do work dW in expanding the gas. Where as Cv has only one function of changing the internal energy of the gas..by awais
Cv is a for a constant volume, and there is therefore no work done in the expansion whereas as Cp accounts for the work done by the gas during its expansion, as well as the change in its internal energy. Thusly Cp is generally bigger than Cv. Intuitively this would be very simple to work out yourself. We used to have to work this out ourselves back in my day, not just resort to cheap answers on the interweb.
