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.

Is there any cathodic protection for offshore cranes?
According Cp if ur Crane is not contacting with any electrolyte like water, soil, means ther is no cp for atmospheric corrosion.
What is Central tendecy?
There are three statistical measures of "central tendency" - mean, median and mode. Combined, they give a picture of how close the data values cluster around a single "average" value. Normally, when someone talks of AVERAGE they are talking about the MEAN - where you add all the values and divide by the number of data points. But that value can be greatly affected by extreme values (e.g., the Mean of the following numbers: 3, 4, 4, 5, 4, 3, 27, 4, and 4 would be skewed by that one value that is not close to most of the others). The MODE of the numbers I gave, however, is the value that occurs most frequently - 4. The MEDIAN, the point where half the values are higher and half are lower, would also be 4. So, you see, the Central Tendency would be toward the value 4 and there is a strong Central tendency in this set of values. You could have a different set of numbers (e.g., 3, 27, 118, 11, 2, 963, 48) and while you could calculate an arithmetic mean, you could see that it wouldn't be too useful since there is no real Central Tendency of the data.
Applications of center of pressure?
As the intensity of pressure increases with depth so for an inclined surface CP is bellow CG. Center of gravity : a point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the center of mass.
What are the advantages of scotch yoke mechanism over slider crank mechanism?
Reduced friction, smoother operation, more power delivered. A big disadvantage is that the slot in the yoke wears rapidly due to sliding friction.
What is the Fracture Toughness Values of Stainless Steel 304?

Why the value of cp and cv is different for different gases?
The values of cp (specific heat at constant pressure) and cv (specific heat at constant volume) are different for different gases because the way gases store and release heat energy varies depending on their molecular structure and behavior. Gases with different molecular compositions have different ways of transferring and storing energy, leading to variations in their specific heat capacities.

How do you derive the equation cp-cv equals R?
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.
Does the relation Cp minus Cv equal R hold true for solids and liquids Why or why not?
No, the relation Cp - Cv = R does not hold true for solids and liquids. This relation is specific to ideal gases and is known as the Mayer relation. In solids and liquids, the heat capacities are influenced by factors like molecular interactions and phase changes, leading to different relationships between Cp, Cv, and R.
Why Cp is greater Cv?
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

Explain how you can determine the atomicity of a gas?
To find the atomicity of an ideal gas you can use γ = Cp/Cv.
Why has a gas two values of molar heat capacities?
A gas can have two values of molar heat capacities, (C_p) and (C_v), because heat can be absorbed by a gas either at constant pressure ((C_p)) or at constant volume ((C_v)). The difference in these values is due to the fact that energy input can either contribute to increasing the internal energy of the gas or do work on the surroundings by expanding the gas.
Why general gas equation is used in the proof of cp-cvR?
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.
What is suspecious pointer conversion error?
Assignments between different types of pointer. Example: int i, *ip; char c, *cp; ip= &c; ip= cp; cp= &i; ip= cp; /* all wrong */
