The big reason is because air is air, and water is water. The second reason is because air is compressible, while water cannot be compressed.
What that means is that if you compress air to twice the pressure, it will be one-half the volume. If you compress water to be twice the pressure, the volume won't change.
water for example.absolute pressure; gauge pressure; atmospheric pressure
Different places have different elevation, and different elevations have different air pressure. It is the ambient air pressure which affects the boiling point of water. Air presses down on water, making it harder for the water to form bubbles. Less pressure produces a lower boiling point. More pressure produces a higher boiling point.
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
Pure water boils at 100 degrees at atmospheric pressure.
Both the can in the pan of water and the mercury barometer function based on the principle of atmospheric pressure. In both cases, changes in atmospheric pressure will cause a corresponding change in the level of water or mercury in the device. The height of the water or mercury serves as an indicator of the atmospheric pressure at that moment.

Atmospheric pressure is the force exerted by the weight of the air in the atmosphere, while water pressure is the force exerted by the weight of water in a body of water. Atmospheric pressure decreases with altitude, while water pressure increases with depth. Atmospheric pressure is measured in units like atm or pascals, while water pressure is typically measured in units like pounds per square inch (psi) or pascals.
The atmospheric pressure is lower. When you are boiling the water, the water's vapour saturation pressure is able to match the atmospheric pressure faster therefore it boils faster and at a lower temperature.
Yes, the pressure inside the collection container will be exactly equal to the atmospheric pressure if the water level in the collection container is level with the rest of the water. If the atmospheric pressure is different, then the pressure inside the collection container will be different, and that will affect how you calculate the amount of gas collected. If the pressure is different due to the difference in altitude of the location, or even different weather, the results will be different. Simply measuring the atmospheric pressure with a barometer will allow you correct for any such differences.
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c
The total pressure of water is calculated by adding the atmospheric pressure to the pressure due to the depth of the water column using the formula: total pressure = atmospheric pressure + (density of water × acceleration due to gravity × depth of water).
Different places have different elevation, and different elevations have different air pressure. It is the ambient air pressure which affects the boiling point of water. Air presses down on water, making it harder for the water to form bubbles. Less pressure produces a lower boiling point. More pressure produces a higher boiling point.
The saturation temperature of water at standard atmospheric pressure is 100 degrees Celsius.

The boiling point of water depends on the purity of the water as well as the atmospheric pressure.
Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point, while water pressure is the force exerted by water on an object or surface due to the depth of the water. Atmospheric pressure decreases with altitude, while water pressure increases with depth.
When pressure greater than atmospheric pressure is applied to pure water or a solution, the boiling point of the water/solution will increase. This means that the liquid will need to reach a higher temperature before it boils. Conversely, if the pressure decreases below atmospheric pressure, the boiling point will decrease, requiring a lower temperature for boiling to occur.
