Water vapor will increase in exhaled air compared to inhaled air because the air we breathe in gets warmed and humidified as it passes through our respiratory system, leading to an increase in water vapor content when we exhale.
The temperature decreases as the gas (vapour) turns back into a liquid. For instance, the hot water vapour from a kettle can be cooled so as to condense back into water.
H2C2O4, also known as oxalic acid, will decrease the pH when added to water. This is because oxalic acid is a weak acid that will dissociate in water to release hydrogen ions, leading to an increase in H+ concentration and a decrease in pH.
When you add baking soda to water, the temperature of the water may decrease slightly due to an endothermic reaction that occurs as the baking soda dissolves. This is because the dissolution of the baking soda requires energy, which can be absorbed from the surrounding water, causing a slight decrease in temperature.
Condensation of water vapor is a physical change, not a chemical change. It involves the transition of water vapor into liquid water due to a decrease in temperature, without any change in the chemical composition of water molecules.
The presence of impurities on the surface of water disrupts the hydrogen bond network, causing a decrease in the rate of evaporation of water molecules. This reduction in evaporation leads to a decrease in vapor pressure, resulting in the need for higher temperatures to reach equilibrium between liquid and vapor phases, hence increasing the boiling point of the water.
exhaled water vapor will be greater than inhaled water vapor
because it condenses into water when your hot breath is exhaled onto a cold object.

Exhaled air is saturated with water vapor because our lungs add moisture to the air as it passes through the respiratory system. This moisture comes from the lining of the lungs and airways, as well as from water that is evaporated from the blood flowing through the lungs.
Trace amounts of water vapour are also exhaled, alongside the carbon dioxide.
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
Well, if you increase the pressure of the atmosphere, isothermally, around water high enough, then you will overcome the 'vapour pressure' of the water, or the pressure of the water's surface back on the atmosphere to put is very, very simply. SOOOO, if you increase gravity, then you increase atmospheric pressure, which will condense any water vapour in the air. You can decrease gravity to see that the vapour pressure of the newly condensed liquid water will overcome the atmospheric pressure and vaporize. Keep in mind this works in standard conditions, not at extreme temperatures and pressures.
No. The exhaled air contents more water vapour. The exhaled air is almost saturated with water vapour.
Helium is a relatively light gas which is lighter than air at ground level. Exhaled air contains a lot of water vapour and carbon dioxide relative to normal air. Since ground level air is less dense than helium, adding water vapour and carbon dioxide makes exhaled air even more heavier than helium.
Increase:- When water vapour condenses out of the air to form water droplets, the energy (the latent heat) in the water vapour is released into the surrounding air and the air is warmed.
Humidity is basically the amount of water vapour in the air. And evaporation is the vaporization of water into water vapour. So when the humidity is high there are already plenty of water molecules in the air so the water which gets vapourized into water vapour takes time to fill the gaps in the atmosphere and thus rate of evaporation is slow.
