Forms of condensation: dew, frost, fog, and mist

Question 1MediumLevel 88

If mist gradually becomes denser, what may it appear to become?

AFrostBDewCFogDHot wind

Question 2MediumLevel 88

What is the most common shared idea while studying these forms of condensation?

AWater vapour cooling and changing into droplets or iceBRocks heating and meltingCComplete drying of seawaterDAir removing gravity

Question 3MediumLevel 88

Why can fog appear more over bridges or open fields in the morning?

ABecause open areas can cool quickly at night and saturate nearby moist airBBecause bridges always destroy water vapourCBecause open fields have no airDBecause fog forms only underground

Question 4MediumLevel 89

If grass surface cools to the dew point at night which form is most likely to develop?

AFrostBFogCDewDMist

Question 5MediumLevel 89

Compared with dew which additional condition is necessary for frost formation?

ASurface temperature being below freezing pointBSurface being very hotCAir being completely dryDRise of sea waves

Question 6MediumLevel 89

What is the main exam-worthy difference between mist and fog?

ADifference in colourBDifference in air pressureCComplete difference in temperatureDDegree of reduction in visibility

Question 7MediumLevel 89

Why does the chance of dew formation increase on a clear calm night?

ASurface can cool more by radiationBWater vapour always disappears from airCThe Sun gives more heat at nightDGround changes into sea

Question 8MediumLevel 89

Why can fog collect more in valleys during morning?

AValleys are always hotBValleys have no airCCold dense moist air can remain in valleysDValleys destroy water vapour

Question 9MediumLevel 89

If a white icy layer appears on plants which process may be linked with it?

AEvaporation of liquid dropletsBDeposition of water vapour into ice crystalsCSplashing of sea saltDHeating of dust

Question 10MediumLevel 89

What is the direct cause of reduced visibility in fog?

AIncrease of oxygen in airBGreater heating of groundCBreaking of rocksDScattering of light by tiny water droplets

Question 11MediumLevel 89

What role does a water source play in morning mist near a river or lake?

AIt supplies moisture to the airBIt makes air completely dryCIt removes sunlightDIt turns air into rock

Question 12MediumLevel 89

Why can dew disappear after sunshine begins?

AIt becomes frost permanentlyBIt evaporates and becomes water vapourCIt changes into rockDIt removes soil

Question 13MediumLevel 89

What is the main similarity between dew and frost?

ABoth form only in the seaBBoth form due to earthquakesCBoth are related to water vapourDBoth are dry dust

Question 14MediumLevel 89

If air is moist but the surface is not cold enough what problem will occur in dew formation?

ADew will immediately become frostBWater vapour will go to the seaCSunlight will stopDThe surface will not reach dew point

Question 15MediumLevel 89

In what form is water found in both fog and mist?

AAs tiny droplets suspended in airBAs stones inside EarthCAs ice mountains below sea levelDAs dry sand

Question 16MediumLevel 89

Droplets forming on a cold window from moist indoor air give an example of what?

AErosionBTranspirationCCondensationDSalinity

Question 17MediumLevel 89

Why can very strong wind prevent dew formation?

ABecause it changes land into seaBBecause it switches off the SunCBecause it changes soil into iceDBecause it prevents a cool moist layer near the surface

Question 18MediumLevel 89

What is the practical meaning of mist being lighter than fog?

AVisibility is generally better in mistBMist has no dropletsCMist is only rockDMist always changes into frost

Question 19MediumLevel 89

If there are liquid droplets on leaves in the morning but no white icy layer which form is it?

AFogBFrostCDewDSnowfall

Question 20MediumLevel 89

If water vapour directly changes into ice crystals on a cold surface which form will develop?
