For the same gas, more density means more molecules per unit volume.
Density: As gas density increases, the molecules become closer to each other. Therefore, they are more likely to run into each other, so the mean free path decreases.Increasing the number of molecules or decreasing the volume will cause density to increase. This will decrease the mean free path.Radius of molecule: Increasing the radius of the molecules will decrease the space between them, causing them to run into each other more. Therefore, mean free path decrease.Pressure, Temperature, and other factors that affect density can indirectly affect mean free path.
If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
When wavelength decreases, frequency increases, and when wavelength increases, frequency decreases. The product of (wavelength) times (frequency) is always the same number ... the speed of the wave. So when one of them changes, the other one must change in the opposite direction in order for their product to remain unchanged.
The period and frequency of a wave are inversely related, i.e. the period is the time it takes for wave to go through a cycle, and the frequency is the number of cycles in a certain time period. For example, a wave with a period of 0.5 seconds would have a frequency of 2 per second. Since these properties are the inverse of each other, than they will be opposite when changing. If the period decreases (i.e. gets shorter, faster) than the frequency increases. Or vice versa.

Number of stomata per unit area decreases as CO2 level increases.

Atomic radius are increase so density change by going down the periodice table
The great the density the higher the air pessure.
Increases
Volume = Mass/Density. In a larger container the mass of the gas remains unchanged, the density decreases so the volume increases.
If you freeze a given quantity of water, the volume increases. When it melts, the volume decreases. The number of molecules remains the same.
The atomic radius decreases from left to right and increases from top to bottom
In this case the atomic number decrease by 2.
As the number of bulbs in a series circuit increases, the current decreases. As the number of bulbs in a parallel circuit increases, the current increases.
It increases the kinetic energy of the molecules (APEX)
