Formule inverse del volume specifico. If the size of the chamber remains constant and some atoms are removed, the density decreases and the specific volume increases. 2. Furthermore, the equation for the volume of an ideal gas is V = nRT /P while the equation for the specific volume of an ideal gas is ν = RT/PM. With regard to the nature of these two properties, volume is an extensive property. The specific volume of the original tank is the same as the specific volume in each half. si può ricavare il volume del corpo conoscendone il volume specifico e la massa. {\displaystyle \ \nu ={\frac {RT}{P}}} This means this parameter depends on the temperature and pressure of the thermodynamic system. Specific volume is the inverse of the density of a substance; therefore, careful consideration must be taken account when dealing with situations that involve gases.

Take Exam Figure 01: Volumetric Flasks are Useful to Measure the Volume of Liquids. Available here, 1.’860478′ by schlayphe (CC0) via pixabay. Extensive properties are those that do depend on the size of a thermodynamic system. Small changes in temperature will have a noticeable effect on specific volumes. This equation, Reduced Specific Volume, is used in 1 page Show. 's' : ''}}. If the density of a substance doubles, its specific volume, as expressed in the same base units, is cut in half. Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume. Specific volume is inversely proportional to density. However, if the temperature is changed to 1160 Rankine, the specific volume of the super heated steam would have changed to 0.2765 in3/lb, which is a 59% overall change. the unit of measurement is (m3/kg). v da = specific volume of moist air per mass unit of dry air (m 3 /kg) V = total volume of moist air (m 3) m a = mass of dry air (kg) If one sets out to determine the specific volume of an ideal gas, such as super heated steam, using the equation The values were recorded at standard temperature and pressure, which is defined as air at 0 °C (273.15 K, 32 °F) and 1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr).
If the size of the chamber remains constant and new atoms of gas are injected, the density increases and the specific volume decreases. Choose an answer and hit 'next'. Volume is a thermodynamic property of a substance.

In definitiva, il volume specifico in (dm 3 /kg) o in (cm 3 /g) si ottiene moltiplicando il volume specifico espresso in m 3 /kg per 1000. 1. The specific gravity of substance X with respect to Y is 0.569, while the specific gravity of Y with respect to X is 1.756. Notice that the average specific volume of blood is almost identical to that of water: 0.00100 m3/kg.[2]. Knowing the specific volumes of two or more substances allows one to find useful information for certain applications. [3], The table below displays densities and specific volumes for various common substances that may be useful. Final Exam Introduction to Engineering Status: Not Started. In that case, the specific volume would equal 0.4672 in3/lb. Volume is a thermodynamic state of a substance. All other trademarks and copyrights are the property of their respective owners. Furthermore, the equation for the volume of an ideal gas is V = nRT /P while the equation for the specific volume of an ideal gas is ν = RT/PM. In other words, it is the ratio of a substance’s volume to its mass. All rights reserved. The key difference between volume and specific volume is that volume is an extensive property whereas specific volume is an intensive property. [4], * values not taken at standard temperature and pressure, https://en.wikipedia.org/w/index.php?title=Specific_volume&oldid=982222677, Creative Commons Attribution-ShareAlike License. Using the formula V=M x SG, the volume of 100 grams of sulfuric acid = 184 ml. Plus, get practice tests, quizzes, and personalized coaching to help you succeed. 6.67 x 103 kg / m3 and 150 m3 / kg, respectively, 6.67 x 103 m3 / kg and 150 kg / m3, respectively, 150 m3 / kg and 6.67 x 103 kg / m3, respectively, 150 kg / m3 and 6.67 x 103 m3 / kg, respectively. The equation for the specific volume is as follows: ν is the specific volume, V is the measured volume and m is the mass of a substance. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } }
For a substance X with a specific volume of 0.657 cm3/g and a substance Y with a specific volume 0.374 cm3/g, the density of each substance can be found by taking the inverse of the specific volume; therefore, substance X has a density of 1.522 g/cm3 and substance Y has a density of 2.673 g/cm3. Specific volume is the volume of a unit mass of a substance. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons If the chamber is made smaller without allowing gas in or out, the density increases and the specific volume decreases. All rights reserved. The changes of this volume are useful in producing a work. Density decreases and specific volume increases. Pressure and temperature have an effect on the volume of a given mass of gas. Sciences, Culinary Arts and Personal Therefore, the unit of measurement for volume is m3 and the unit of measurement of specific volume is m3/kg. Specific volume is a chemical concept that represents the relationship between mass and volume of a substance. 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. Therefore, the unit of measurement for volume is m 3 and the unit of measurement of specific volume is m 3 /kg. English, science, history, and more. 5. flashcard set{{course.flashcardSetCoun > 1 ? Taking this quiz will confirm your knowledge of the following: To continue your studies on this topic, be sure to review the related lesson titled What is Specific Volume? It is an intensive property of a substance and the reciprocal of the density. Specific volume is the volume of a unit mass of a substance. The specific volume is a fourth of what it was. To convert m3/kg to cm3/g, multiply by 1000; conversely, multiply by 0.001.
where pressure is 2500 lbf/in2, R is 0.596, temperature is 1960 Rankine. We can obtain the specific volume of an ideal gas using the following steps: Volume is a thermodynamic state of substances that refers to the volume of working fluid of a thermodynamic system.
