For the same gas, more density means more molecules per unit volume.
Yes, that's correct. As air density decreases, the number of air molecules in a given volume decreases, leading to a decrease in pressure. This relationship is described by the ideal gas law.

The volume of the object increases when the number of molecules increases because there are more particles occupying a larger space. Additionally, the mass of the object will also increase because there are more molecules present.
The resistivity of a conductor is inversely proportional to the number density (n) of free electrons. This means that as the number density of free electrons increases, the resistivity of the conductor decreases, and vice versa. This relationship is due to the fact that more free electrons provide more paths for the flow of electric current, resulting in lower resistance.
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.

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

A gas (including air) will expand if the temperature increases. That means the same mass of gas will have a larger volume. Since density is mass / volume, that means the density will decrease.

As the number of bonds between atoms increases, the bond angle generally decreases. This is because the additional bonds exert more electron density around the central atom, causing the bonded atoms to be pushed closer together and resulting in a smaller bond angle.
As the number of bonds between two carbon atoms increases, their bond length decreases. This is due to the increased electron density, which pulls the atoms closer together. Bond strength also increases as the number of bonds between two carbon atoms increases.
An increase in the number of molecules increases the frequency of molecular collisions with the container walls. With more collisions per unit time, the average force exerted by the molecules on the walls increases, resulting in an increase in pressure.
Volume = Mass/Density. In a larger container the mass of the gas remains unchanged, the density decreases so the volume increases.
Pressure changes more rapidly with height compared to density. This is because pressure decreases exponentially with height due to the decrease in the weight of air above, while density decreases more gradually with height as a result of the decreasing number of air molecules.
the density decreases because the particles spread out and so less particles occupy the same amount of area meaning the substance is less dense.
