What is colloidal suspension of fine particles in a gas such as air using O R S L in that order?
A colloidal suspension is a mixture where fine particles are dispersed in a gas such as air. O, R, S, and L are the first letters of the terms used in this context: "O" for dispersed phase, "R" for the dispersion medium, "S" for suspension, and "L" for liquid.
How can a humidifier help reduce indoor levels of harmful PM2.5 particles?
A humidifier can help reduce indoor levels of harmful PM2.5 particles by increasing moisture in the air, which can cause the particles to become heavier and settle out of the air. This can result in lower concentrations of PM2.5 particles in the indoor environment, leading to improved air quality.
What is a collodial dispersion in chemistry?
An intimate mixture in which small particles are permanently dispersed throughout a solvent. Milk, for example, is a colloidal dispersion of fats, proteins, and milk sugar in water. The suspended particles are intermediate in size between visible particles and individual molecules.
Particles of carbon what enters the air when wood and coal are burned are called?
Particles of carbon that enter the air when wood and coal are burned are called soot or particulate matter. These tiny particles can contribute to air pollution and have harmful effects on human health and the environment.
What mixtures scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?
These mixtures are colloids or very fine suspensions.
What is the colloidal suspension of fine particles in air caalled?
aerosol
What are three examples of colliods?
Three examples of colloids include milk (a colloidal dispersion of fat particles in water), fog (a colloidal dispersion of liquid water droplets in air), and whipped cream (a colloidal dispersion of air bubbles in liquid cream).
What are the Solvents and solutions in smoke?
Smoke is not a solution, it is a colloidal suspension of very fine particles in air.
What are solute and solvent in smoke?
Smoke is not a solution, it is a colloidal suspension of very fine particles in air.
What is a burst of air that blows harmful particles out of the nose?
A sneeze is a burst of air that is forcefully expelled from the nose and mouth, often to clear irritants and harmful particles.
An aerosol dispenser contains a colloidal dispersion of?
particles suspended in a gas or liquid. When the dispenser is activated, the colloidal dispersion is released as a fine mist or spray. This allows for the efficient distribution of the particles for various applications such as air fresheners, insect repellents, or medications.
What are the application of colloids?
Applications of colloids are unlimited. Colloids find its applications in everyday life phenomena. Some of important applications of colloids are discussed.Purification of waterWater contains colloidal impurities .These impurities can be weeded out by using electrolyte like Alum. Alum is positively charged Al3+ ion which attracts negatively charged colloidal impurities. These neutralized particles settle down and pure water is decanted off. Thus Alum is used to remove dirt and impurities present in the colloidal solution. Food ItemsLarge numbers of food articles which we use in our daily life are colloidal in nature. For example, milk, butter and ice creams are colloidal in nature. MedicineMost of the medicines are colloidal in nature. Colloidal calcium and gold are administered by injections to raise the vitality of human system. Smoke Precipitation using Cottrell precipitatorColloidal particles of Smoke and dust are major source of pollution in big industrial cities. Smoke precipitation is technique of precipitating smoke particles present in air. Smoke particles are the electrically charged colloidal particle suspended in air. To remove these particles from air, Cottrell precipitator is used. Cottrell precipitator uses principle of electrophoreses (movement of colloidal particles under influence of electric field) to weed out smoke particles. Air containing smoke and dust particles are allowed to pass through metal electrodes present inside Cottrell precipitator. These charged particles moves towards oppositely charged electrodes and get deposited there from which they are scrapped mechanicalSewage disposalDirt and mud particles are electrically charged. By applying electric field in sewage tank, dirt particles reach the oppositely charged electrode, get neutralized and are coagulated. These coagulated particles are suspended in solution and are easily removed. Artificial rainColloids find another application in producing artificial rain. Cloud consists of charged particles of water dispersed in air. These particles are neutralized by spraying oppositely charged particles over a cloud. These neutralized particles of water combine to form large water drops. Thus, artificial rain is caused by the aggregation of minute particles of water to form large particles.

How do you take in the harmful particles in the air?
Harmful particles in the air can be taken in through inhalation, where they can enter the respiratory system and potentially cause harm to the lungs and other organs. It is important to minimize exposure to polluted air and use protective measures like wearing masks or using air purifiers to reduce the intake of harmful particles.
Dust and pollen in the air is an example of?
Dust and pollen in the air are examples of particulate matter, which are tiny solid or liquid particles suspended in the air. These particles can affect air quality and can be harmful when inhaled.
What is a collodial dispersion in chemistry?
An intimate mixture in which small particles are permanently dispersed throughout a solvent. Milk, for example, is a colloidal dispersion of fats, proteins, and milk sugar in water. The suspended particles are intermediate in size between visible particles and individual molecules.
