this air is warmer because it is the heat coming out of your body (usually warmed 98.6 degrees.)
Your body warms and moistens the air that passes into the lungs to make it easier for oxygen to pass into the bloodstream.
The air must be warmer than what it is touching and there must be moisture in the air.
Colder air is more dense than warmer air. That is why nobody every flies in a cold-air balloon.
You dont breathe air pressure. You breathe air. It is harder to breathe because of the low air pressure due to the higher elavation.
If there is no fan to pull the air in, fresh air must come into a convector heater from below. It is drawn in because the air heated by the heating element is warmer and therefore lighter than the colder air below it. So the warmer air rises to leave the convector heater from the top.
We can say that air we breathe out is warmer, because if we breathe out on a mirror we can see droplets of water which means air is hotter compared to normal room temperature air because the room air condenses. Exhaled air is warmer than inhaled air because its the same room temperature air which we have taken in.
Because your body is warm, so Body Heat causes this.
Depends on which temperature it held to start with. In a Sauna exhaled air will be colder, in a walk-in freezer exhaled air will be warmer. How about in a lift? Where isn't a relevant factor, only ambient temperature is. If the ambient temperature is colder than body core temperature, then exhaled air will be warmer. If ambient temperature is warmer than body core temperature then exhaled air will be colder.
Warmer air can carry more "dissolved" water(water wapour) than colder air can. When you breathe out moist, body-temperature air into colder air that excess water vapour condenses into tiny droplets, which create the fog that you see.
If air is holding as much moisture as it can, colder air holds less than warmer.
at night the air over the water is warmer than the air over the land
If moisture content is the same, it would be warmer.
No. If the air is warmer than the ground any movement of heat by conduction will be from the air to the ground.
When the air is cold outside, you can see your breath as a smokey wisp in front of you. This is because your breath is warmer than the surrounding air.
because of air temperature
the air is warmer because the sun's rays hit the equater more directly and because it is warmer it becomes more dense
If the air in the in the upper atmosphere were warmer than the water vapor that was continued in the air would make the earth colder in the air.
