Why does moist in the mirror after you blow it?
The moist you are talking about is nothing but the water vapour that one releases, every time one exhales. As already know, when we breathe in, the air that enters gets humidified as it passes through the nasal passages. Hence, the air exhaled, or breathed out, contains considerable percentage of water vapour. Now, this water vapour exhaled out, initially is at body temperature, i.e., 37.5*C. On coming out through exhalation, the vapour soon cools down and condenses on the nearby mirror glass surface. Hence, the moist is seen.
Why water vapour in air plays an important role in heating and cooling of air?
So when they turn into clouds the water vapour condences into tiny droplets of water and it gets bigger and bigger it falls as rain
What is the amount of water vapour called in the air?
That is called humidity.
Why a glass of cold water perspires with water drop when exposed to air?
Condensation of water vapour in the atmosphere into water droplets on the surface. The surrounding air contains water vapour. When the air touches the glass it becomes cooler and can no longer contain so much water, so it condenses out onto the glass.
Which air is heavier out of inhaled air and exhaled air?
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
What is occurring when you can see your breath on cold days?
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.
Why exhaled air has more water vapour?
No. The exhaled air contents more water vapour. The exhaled air is almost saturated with water vapour.
The excretory system why do you see your breath on a cold day?
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.
How go you know that the air exhaled by us contains water vapour?
because it condenses into water when your hot breath is exhaled onto a cold object.
When air is saturated?
when it holds all the water vapor it can hold
When air is saturated it cannot hold?
… any more water vapour.
Why is exhaled air more dense than helium?
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.
How do you get dew point?
Cool air at a constant pressure until it is saturated with water vapour
Explain the amount of various gases in an inhaled and an exhaled air?
Inhaled airNitrogen: 78%Oxygen: 21%Carbon Dioxide: 0.04%Water Vapour: 0.96%Exhaled AirNitrogen: 78%Oxygen: 17%Carbon Dioxide: 4%Water Vapour: 3%
What is it called when air can hold no more water vapour?
When air can hold no more water vapor, it is said to be Saturated. It has a Relative Humidity of 100%
How does dew get on the grass?
As air gets colder, the amount of water it can hold as water vapour goes down. It reaches a point where the air releases the water as dew but stays saturated with water vapour. If this point is below the freezing point of water, it is deposited as frost.
