When a warm surface hits a cold vapour does this form condensation?

Yes - the practical experience of many photographers confirms that if you take warm equipment outside into cold conditions that condensation will form on the surface of eg the lens. Interestingly, this result is not predicted by basic theory. In almost every explanation of condensation that you will find, condensation occurs when warm air is cooled by a cooler surface so that the air drops below its "dew point" and can no longer contain all of the water that it is carrying.
So, the condensation from cold air on a warm surface is not expected, but is a very real actual effect. Various scenarios can be proposed to explain this apparent anomaly. So far I have not met a satisfying explanation BUT the effect is real.

When is condensation more likely to occur?
Condensation usually occurs on a surface that is cooler than the adjacent gas. A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of its liquid or solid phase at the temperature of the surface where the condensation is to occur. The process causes the release of thermal energy. Condensation occurs on a glass of cold water on a warm, humid day when water vapour in the air condenses to form liquid water on the glass's colder surface. Condensation also accounts for the formation of dew, fog, rain, snow, and clouds.
Why do water droplets form on the inner wall of a covered cup of hot water?
Because it's mixing between either water vapour and condensation or steam and condensation(most likely)
What are 5 situations in which condensation can be observed?
Basically, condensation can form when liquid is added to a gas, or when a saturated sample is cooled. Some examples are: - water vapor condenses on the outside of a cold can of soda, or a glass of iced tea - a person exhales into cold air, or onto a cool hard surface - fog forms when warm moist air passes over cooler water or land - clouds form when warm air rises into cooler air above it - nucleation points are added to supersaturated air (forms water or ice)
What does the sun have to do with evaporation?
The heat from the Sun, aided by the wind, would evaporate water from the surface of the oceans. The water vapour would rise to form clouds. It is part of the 'Water Cycle'.
Is water freezing to form ice a chemical or physical change?
well ! actually it is a very simple phenomenon.....because of the icy cold water, the air around it gets condensed when it comes close enough. consequently, the condensation causes the water vapors in the air to change into droplets that then appear on the surface of the container of that icy cold water...
Condensation occurs when?
Condensation occurs in cold when water vapour condense to form tiny droplets of water.
Why does dew form on a cold soft drink can?
Condensation forms on any cold container because heat is transferred from water vapour in the air near the container to it, which warms the container and cools the vapour. The vapour turns back to liquid and condenses on the container surface.
What conditions must be present to frost to form?
water vapour/ cold /and a condensation medium

Condensation also accounts for the formation of dew, fog, rain, snow, and clouds.
What is the process of water droplets form on cold surface?
because that is rihfhr
How Do Water Droplets Form?
water droplets form when a cold surface touches a hotter surrounding air and condenses to form water droplets
What is condensation in a water cycle?
When the sun evaporates water from the earth's surface the water vapour rises into the air. As it rises the air becomes colder.When the water vapour becomes cold enough it condenses (like water on the outside of a cold drink) to form liquid water again. These tiny water droplets form clouds. When enough of the droplets merge together they get too heavy to float and they fall as rain (precipitation).
What is difference between vaporization and condensation?
Condensation is where a vapour (gas) is cooled, and droplets of liquid form. Vapourisation is where a liquid is heated, and the liquid turns into vapour (gas).
What is it called when water vapour joins together to form droplets?
Condensation.
If a cold empty glass is suddenly placed outside on a hot humid day?
Condensation will form on the surface of the glass.
What is liquid that condenses from water vapor on surface?
Condensation
What is the term for when water rises up to form clouds?
evaporation is when water vapour rises up and condensation is when water vapour turns into clouds
