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. However, specific volume is an intensive property. ...
Also referred to as the molar volume , symbol V m , is the volume occupied by 1 mole of a substance (chemical element or chemical compound) at a given temperature and pressure. It is equal to the molar mass ( M ) divided by the mass density (蟻). It has the SI unit cubic meters...
One mole of an ideal gas expands adiabatically from 200 K to 250 K. If the specific heat of the gas at constant volume is 0.8 kJ kg-1 K-1. then the work done by the gas is r6 oo 200K od 250 Ks'gog)63=0.8kJkgK )Options:20J120kJ40J40kJ A 相关知识点: 试题来源: 解析 ...
Absolute humidity is the actual mass of water vapor present in the air water vapor mixture. Air - Humidity Ratio The mass of water vapor present in moist air - to the mass of dry air. Humid Air and the Ideal Gas Law Pressure, temperature and volume in a perfect ideal gas like ...
The changes in specific internal energy and specific enthalpy of an ideal gas are given by Eqs. (3.38) and (3.42). The constant pressure and constant volume specific heats of air are found in Table 3.7 (or Table C.13) as cp = 0.240 Btu/lbm · R and cv = 0.172 Btu/lbm · R. Th...
To determine whether the specific heat of a gas can be negative, let's analyze the concept step by step.Step 1: Understand the Definition of Specific Heat Specific heat (s) is defined as the amount of heat (Q) required to chang
Find the molar specific heat of the processp=aTfor a monoatomic gas, a being constant. View Solution The molar specific heat at constant volume of gas mixture is13R6. The gas mixture consists of View Solution If the molar specific heat capacity at constant volume of an ideal gas isCv=32...
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 ...
The second specific volume equation usually is applied to liquids and solids because they are relatively incompressible. The equation may be used when dealing withgases, but the density of the gas (and its specific volume) may change dramatically with a slight increase or decrease in temperature. ...
