why do water droplets form on the outside of containers filled with something cold?

Question

Books tell me it's condensation, but that's not too much to go with. Thanks.

Answer 1

It is condensation, so what would help in explaining further is an understanding of dew point.

All air contains water vapor of varying quantities. The dew point indicates the amount of moisture in the air. The higher the dew point, the higher the moisture content of the air at a given temperature. Conversely, the dew point of humid air will be higher than the dew point of dry air.

Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure.

Condensation of water vapor begins when the temperature of air is lowered to its dew point and beyond. The dew point, like other measures of humidity, can be calculated from readings taken by a hygrometer.

Since the cool matter inside the container causes a lower temperature than the surrounding air, it brings the air in contact with the surface below its dew point, the water vapor leaves the gaseous state and collects water droplets on the surface of the container.

Answer 2

The lower temperature on the surface of the container consenses moisture present in the air on the surface of the container.

You don't see this happening in dry days much, or on insulated containers because in dry days, very little moisture in the air will lead to little condensation. On insulated containers, the surface temp will be equal to the environment's, so no condensation occurs.

Answer 3

Very fine particles of water suspended in the air is measured as humidity. . If it comes in contact with something cooler than the air temp it will turn back a visible moisture. same principle when it rains Warm air containing lots of moisture mixes with cool air The water particles form closer bonds and ....Rain drops

Answer 4

its the act of condensation....water vapor releases its water when the temperature of the air reaches a level that allows the molecules to give up its vapor and be converted from a gas to a liquid....

Answer 5

the reduction in temperature causes surface moisture to condense

Answer 6

in case you THREW a coin onto somebody's head then sure you're able to die, as a results of fact the terminal velocity of the coin TRIPLES and easily by this formulation: terminal velocity = (extra stress x gravitational ability capability) / 3. in case you throw a water droplet, you're able to desire to factorise the density of the O2 molecule in case you like that guy to die. different concerns comprise, density of the guy's head, air stress and intermolecular forces.
