The common cold is caused by a rhinovirus, and it is spread through aerosolized droplets (the air) via coughing and sneezing. It is also a rather hardy little virus that can be passed on inanimate fomites (hard objects like door handles and elevator buttons). This is why you should cover your mouth and nose when coughing or sneezing and why you should wash your hands regularly.

What are some diseases spread by air?
Influenza and the common cold can be spread by air, among other routes.
Your heater in your jeep only blows cold air why is this?
The most common reason a automobile heater blows cold air is the water level is low. Check the water level and fill to the appropriate level.
Which is less dense cold air or cold water?
cold air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.
Does ice melt fastest in cold water cold air warm air or warm water?
Warm air and warm water. Cold air and cold water keep ice cooler longer.
Why does cold water in a tube sink to the bottom of room temperature water?
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
Why does hot air hold more water vapour than cold air?
Because the molecules in the hot air are more spread out, allowing water to easily form within the gaps of the molecules. Cold air is more dense and does not allow water to form easily between the molecules.
Is warm air less dence than cold air?
Yes, warm air is less dense than cold air. As air warms up, its molecules gain energy and spread out, decreasing the air's density. Conversely, cold air molecules lose energy and clump together more closely, making cold air denser.
What makes tap water cold?
the air make the water cold
Can warm air hold less water vapor than cold air?
no, warm air holds more water vapour than cold air
What is happening when water droplets appear on the outside of a cold glass of water?
The air has moisture (water dissolved in the air). The amount of air that can be carried in the air depends on the temperature. Warmer air can hold more water in it than cold air. When the cold glass is exposed to the air, the air touching the glass gets cold, is no longer able to hold as much water and the water in the air condenses (comes out of solution) on to the outside of the glass.
Why does heating of cold air reduce humidity?
Heating the air reduces the relative humidity. It doesn't change the amount of watervapor in the air. But warm air is able to hold more water vapor than cold air can, sowhen you heat the air, the air becomes 'less full' of water vapor, which means lowerrelative humidity.
Is it possible to freeze water with just cold air?
Yes, if the air is cold enough.
