What do we mean by reaching 100% relative humidity? Is that we reach the utmost vapor pressure at that particular temperature of liquid? Or something else.
If I have 2 half filled water bottle, in one I have a comparatively cooler water than other , does both bottle empty space above water contain same amount of water vapor ? Vapor pressure increase by increase in volume of vapor or the more speedy(more collisionš„) evaporation of water molecule due to high temperature?
I can't understand it, what actually 100% relative humidity means! Does is the maximum amount of vapor air contain at any temperature (like seat fill completely) or it is the reaching point of equilibrium of vapor at a particular temperature where rate of evaporation is equal to rate of condensation and no further vapor it can contains until an new equilibrium is set by changing temperature of liquid?

Relative humidity is a measure of how much moisture is in the air relative to the maximum amount of moisture that the air can actually hold at that pressure and temperature. So 100% relative humidity means that there is as much moisture in the air as it can hold.
Therefore, 100% relative humdity at one pressure and temperature represents a different amount of absolute water vapour compared to 100% relative humidity at another pressure and temperature.
