Is smoke an example of condensation nuclei?
Floating in the air are millions of minute salt, dust and smoke particles known as condensation nuclei which enable condensation to take place when the air is just saturated.
Is an example of cloud condensation nuclei?
Examples of cloud condensation nuclei include sodium chloride (NaCl) and ammonium sulfate ((NH4)2 SO2), whereas the clay mineral kaolinite is an example of an ice nuclei.
What are condensation nuclei quizlet?
Condensation nuclei are very small (about 0.2 – 10.0 microns) particles light enough to remain suspended in the air. Condensation nuclei are formed from a variety of sources including dust, pollen, smoke, salt from ocean spray and sulfates.
What is condensation nuclei?
condensation nucleus, tiny suspended particle, either solid or liquid, upon which water vapour condensation begins in the atmosphere. Its diameter may range from a few microns to a few tenths of a micron (one micron equals 10-4 centimetre).
Is pollen a condensation nuclei?
It is found that while pollen grains are only moderately hygroscopic, they can activate at critical supersaturations of 0.001% and lower, and thus pollen grains will readily act as cloud condensation nuclei.
Which of the following is not a type of condensation?
The correct answer is Sleet.
Which act as a nuclei for cloud condensation?
Cloud condensation nuclei (CCNs), also known as cloud seeds, are small particles typically 0.2 µm, or 1/100 the size of a cloud droplet on which water vapor condenses. Water requires a non-gaseous surface to make the transition from a vapor to a liquid; this process is called condensation.
What are the types of condensation nuclei?
There are two broad categories of condensation nuclei: hygroscopic and hydrophobic. Hygroscopic nuclei are "water seeking" nuclei. Water vapor condenses on hygroscopic surfaces readily even when the relative humidity is considerably lower than 100 percent. Salt is an example of a hygroscopic particle.
Which of the following are sources of cloud condensation nuclei?
Cloud condensation nuclei promote condensation of water vapor at temperatures above and below the freezing point of water. CCN allow cloud droplets to grow and condense as condensation continues. Natural sources of CCN include ocean spray, volcanic eruptions, and forest fires.
What are 3 types of condensation nuclei?
Cloud condensation nuclei (also known as cloud seeds) are small particles typically 0.2 µm, or 1/100th the size of a cloud droplet on which water vapor condenses.
What is example of condensation?
Clouds in the Sky To see another example of condensation, all you have to do is look up at the sky. Clouds are formed as a result of water vapor cooling in the atmosphere. As the temperature of the water vapor falls to the dew point or below, it condenses to become tiny water droplets.
Which of the following is an example of condensation?
Examples of Condensation: 1. Having a cold soda on a hot day, the can "sweats." Water molecules in the air as a vapor hit the colder surface of the can and turn into liquid water.
Which of the following is not the form of condensation?
The correct answer is Sleet. The conversion of water vapour into the water is called condensation.
What are condensation nuclei and ice nuclei?
The liquid and solid particles that readily promote freezing and ice crystal growth are typically in the 0.05–1 μm diameter size range; they are referred to as cloud condensation nuclei (CCN) and ice nuclei (IN), respectively.
Is are a source of cloud condensation nuclei quizlet?
Cloud condensation nuclei promote condensation of water vapor at temperatures above and below the freezing point of water. CCN allow cloud droplets to grow and condense as condensation continues. Natural sources of CCN include ocean spray, volcanic eruptions, and forest fires.
Which of the following is the most common condensation nuclei?
The most common types of condensation nuclei are crystals of salt, particulate matter formed by the combustion of fossil fuels , and dust blown up from the earth's surface.
What are the 4 types of condensation?
After condensation the water vapour or the moisture in the atmosphere takes one of the following forms — dew, frost, fog and clouds.
What are examples of condensation polymers?
Examples of natural condensation polymers include cellulose, starch, and polypeptide chains of proteins. Several synthetic condensation polymers discussed include nylon, kevlar, polyester, Bakelite, Melamine, polycarbonates, polyurethanes, epoxies.
What is the two example of condensation?
Morning Dew – This happens when the moisture present in the air condenses on the grasses and leaves cooling overnight. Droplets on can or bottle – The cold surface of your can or bottle causes the moisture in the warm air to condense on its surface. Foggy windshield – The air in your car has moisture.
Which is an example of condensation?
Clouds in the Sky To see another example of condensation, all you have to do is look up at the sky. Clouds are formed as a result of water vapor cooling in the atmosphere. As the temperature of the water vapor falls to the dew point or below, it condenses to become tiny water droplets.
How clouds are formed by condensation?
Clouds are usually produced through condensation – as the air rises, it will cool, and reducing the temperature of the air decreases its ability to hold water vapour so that condensation occurs. The height at which the dew point is reached and clouds form is called the condensation level.

Which one of the following is a condensation polymer?
Answer: (iii) Dacron Dacron is a condensation polymer.
Which process is an example of condensation?
Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
Which of the following is not an example for condensation?
Answer: Evaporating of sea water is not an example of condensation.
Which event is an example of condensation?

Which of the following is a condensation?
Answer: (iii) Dacron Dacron is a condensation polymer. The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units. In these polymerisation reactions, the elimination of small molecules such as water, alcohol, hydrogen chloride, etc.
What is condensation explain with example?
Condensation is the process through which the physical state of matter changes from the gaseous phase into the liquid phase. For example, condensation occurs when water vapour (gaseous form) in the air changes into liquid water when it comes in contact with a cooler surface.
