【一】‘the lower... the faster...’ 是指‘...越低，...就越快’。【二】 the molecular mass of gas 意思是气体分子量；it will diffuse 是指它将扩散。【总结】气体分子量越低（就是越少），它扩散的速度就越快。希望对你有帮助哦。。。```*/\*```...
To answer this, we need to be able to estimate the H2 mass.\nTraditionally, this is done using CO and a few assumptions but the Herschel\nobservations in the FIR make it possible to estimate the molecular gas mass\nindependently of CO. Previous attempts to derive gas masses from dust ...
To solve the problem, we need to find the ratio of the partial pressures of gases A and B given the relationships between their densities and molecular masses.1. Understanding the Ideal Gas Law: The ideal gas law is given b
Based on the ^12CO(2→1) emission line we derived L'CO = (3.4 ± 0.6) × 10^10 K km s^1pc^2, that yields a molecular gas mass of MH2 (αCO/4.3) = (1.5 ± 0.3) × 10^11 M and unveils a gas-rich system with gas(αCO/4.3) ≡ MH /M = 3.3 ± 0.7. The extreme ...
Using theoretical estimates for the scaling of molecular gas mass fraction and halo mass, we estimate the cosmic molecular gas density to be ρ_(z ~ 3)(H_2) = 1.1_(-0.4)^(+0.7) x 10^8 M_⊙ Mpc^(-3). 展开 关键词: galaxies: evolution galaxies: high-redshift ISM: molecules ...
Ions may also be produced by removal of one or more electrons from a molecule using electron ionization (EI). This ionization method is historically the dominant ionization method used in MS (most commonly in gas chromatography–mass spectrometry [GC-MS] instruments) and is still used in some ...
S ection 1 The Kinetic-Molecular Theory of Matter The Kinetic-Molecular Theory of Gas es • An ideal gas is a hypothetical gas that perfectly fits all the assumptions of the kinetic-molecular theory. • The kinetic-molecular theory of gases is based on the following five assumptions: 1. ...

Six Postulates of the Kinetic Molecular Theory of Gases A scientific postulate is a statement assumed to be true unless proven otherwise. Six Postulates A gas consists of very small particles, each of which has a mass. Example: An inflated basketball weighs more than a deflated basketball. ...
