On exhaling carbon dioxide is breathed out along with water vapour.
Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.
Water evaporates into water vapour, and water vapour condenses into water.
No, water vapour is water. Nitrogen is around 72% of the air we breath but is not found in water, steam or vapour.
Water vapour depostion is water vapour transforming directly to ice without condensing first.
You breathe out more water vapour then when you breathe in
Yes They are mammals and have about as much water in their bodies as humans. When they breathe they almost definitely breathe out water vapour. They must drink water at some stage or they will expire.
Yes.

Because its part gas and we breath in oxygen
Because its part gas and we breath in oxygen
Humans exhale more water vapour than they inhale because water vapour is a product of respiration which means that your body creates it so has more to get rid of.
no its just vapor of water if its mixed with another element then yes
You can see water vapour in the air, as when a kettle or pan boils, or when you breathe out into cold air. It depends on the temperature balance between the vapour and the surrounding air.
Transpiration is the evaporation of cellular water (in the form of water vapour) from the stomata in the leaves of PLANTS. Humans are NOT plants.
i don't think humans breathe in any water but they do breath out water
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.
