Yes, the air leaving the lungs has accumulated some of the moisture on the alveolar surfaces (inside of the lungs), this leaves with the exhaled air, making it more humid (more water vapour) than inhaled air.
Aside from this and the higher temperature of exhaled air, it is pretty similar to that being inhaled. The concentrations of carbon dioxide and oxygen have altered also, more carbon dioxide leaves than enters, and more oxygen enters than leaves. This is due to removing carbon dioxide from the blood and taking in oxygen to remove metabolic waste and fuel metabolic processes respectively.
Note that not all the oxygen inhaled is absorbed into the blood, and that the exhaled air contains other gases found naturally in the air such as minute proportions of the noble gases and nitrogen.

What do human beings exhale?
Humans, as well as other animals, exhale carbon dioxide, water vapor and some nitrogen. The water vapor can be seen when breathing on a glass window.
What is a declarative sentence for exhale?
Humans breathe out carbon dioxide and water vapor when they exhale. The relaxation of the diaphragm muscle allows you to exhale, but tightening the chest muscles lets you push air out forcibly, as when inflating a balloon.
What leaves the body when you exhale which is why mirrors get foggy when you breathe on them?
Water Vapor.
Why humans exhale more water vapour than they inspire?
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.
Why you see your breath on a cold day?
What you see is water vapor. The air that you exhale contains water vapor. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapr in the air. (the maximum amount of water vapor that the air can hold at that temperature) The colder the air, the less water vapor it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapor. When the air becomes saturated, (relative humidity is 100%), the extra water vapor will condense, allowing you to see your breathe on cold days.
When the lungs inhale oxygen what does it exhale as a waste?
The lungs largely exhale carbon dioxide and water vapor along with the non-oxygen components of the air taken in (such as nitrogen).
How is water vapor useful to humans?
it isn't

How much water per hour do humans exhale?
About 400 mL of water per day
When you exhale you breathe plus carbon dioxide?
On exhaling carbon dioxide is breathed out along with water vapour.
Why do some animals open their mouths to stay cool?
Some animals cannot perspire (sweat) like humans can. When water evaporates it cools the body. Animals, like dogs, open their mouths and exhale water vapor. This has a similar effect as sweating.
When you exhale you breathe this plus carbon dioxide?
Exhaled breath contains:NitrogenArgonOxygenTraces of other atmospheric gasesWater vapourCarbon dioxideOdorous organicsPheromonesParticulates
