According to the ideal gas law, the specific volume of an ideal gas is directly proportional to its temperature and inversely proportional to its pressure. This means that as temperature increases, the specific volume also increases, and as pressure increases, the specific volume decreases.Post...
The specific volume of gases is calculated using the ideal gas law: v = RT/PMWhat is Specific Volume? What is specific volume? The specific volume definition describes a physical property that relates to the volume of matter divided by the amount of matter. The specific volume is alternative...
In this lesson, you learned that specific volume is a measure of volume divided by mass, or:v = V / mIt's also the inverse of density. For ideal gases, specific volume is the gas constant (0. 08206 L (atm) / mol (K)) represented by R, multiplied by temperature (T), and divide...
simple equation. It may be possible, however, to derive this value from other data and from known values for other properties of certain gases. If the density of a given volume of gas is known, the specific volume may be found by applying the formula v = 1/r, where r is the density...
The heat capacity of a gas depends strongly upon the conditions under which heating is done, whether at constant pressure or at constant volume. Indeed, it was pointed out in Chapter 1 that the ratio C p / C υ is as high as 1.67 for a monatomic gas. It is possible to measure ...
For a process at constant volume, dQv = mcvdT and dV = 0. So, mcvdT = dU or, dU = mcvdT. Now let us consider an ideal gas as the working substance. For a process at constant pressure with the same temperature change dT, we have dQp = mcpdT. As the internal energy U of a...
Enthalpy expresses the results of thermodynamic processes in a system occurring under special conditions. It is a measure of the results due to pressure, volume, and internal energy changes in the system. Its value is given as change in the energy state of the system, that is, as difference...
Specific heat at constant volume, specific heat at constant pressure, specific heat ratio and individual gas constant - R - common gases as argon, air, ether, nitrogen and many more.
