The dry gas pressure when collecting gases over water is calculated by subtracting the vapor pressure of water at the given temperature from the total pressure of the gas collected.
In the Purdue University experiment "Collection of Gas Over Water," the volume of carbon dioxide collected over water is measured by displacing the water and collecting the gas in a calibrated tube. Dalton's Law of Partial Pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas. Since the experiment involves collecting the gas over water, the partial pressure of water vapor needs to be accounted for when measuring the volume of carbon dioxide.
Bubbles form in water bottles due to the presence of gases dissolved in the water. When the bottle is opened or shaken, the pressure changes and the gases are released, forming bubbles.
Bubbles in your water bottle are likely caused by gases dissolved in the water, such as carbon dioxide. When you open the bottle, the pressure decreases, causing the gases to come out of solution and form bubbles.

Air is the mixture of different gases (like oxigen, nitrogen, co2 e.t.c.) & water vapour. Gases are only gases, here is no water vapour. And water vapour is form after the vapourization of water at high temperature.
Glass lids are slid under the gas jar when gases are being collecting. This is so the water vapor is collected.
Gases are most soluble in water under conditions of low temperature and high pressure. Additionally, the solubility of gases in water is often influenced by the nature of the gas itself and its polarity.

Water pressure increases as the water gets warmer. If water is cold, it doesn't provide much pressure because the molecules move slowly.
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).
To clarify a point - a gas is more soluble in cold water than in hot water. I can only surmise that cold water is used in the process of gas collection by downward displacement of water due to the lower vapor pressure of water at the lower temperature - compared to normal room temperature. This would have the effect of collecting drier gas in the collecting cylinder.
Gases, such as water vapor and carbon dioxide, dissolve in magma when it is under pressure deep underground. As the magma rises to the surface and pressure decreases, these gases can come out of solution, leading to volcanic eruptions.
water has a definite volume, but not a shape. The amount of pressure exerted on the water must be displaced around the container, causing a pressure to build up, as water and other liquids cannot be compacted like gases.

No, not all gases are less dense than water. For example, gases like chlorine, fluorine, and carbon dioxide are denser than water at room temperature and pressure.
