What is aerosol state two uses of aerosol?

In general conversation, aerosol usually refers to an aerosol spray that delivers a consumer product from a can or similar container. Other technological applications of aerosols include dispersal of pesticides, medical treatment of respiratory illnesses, and combustion technology.

What were aerosols first used for?

The first use for an aerosol package arose during World War II, but the idea of using low-pressure liquefied gas to atomize droplets of liquid in the air was developed in 1924. Canisters filled with insecticide and propellants were used to protect U.S. servicemen from insects carrying diseases such as malaria.

What are advantages of aerosols?

Aerosol administration gives very efficient and quick relief. The stability of drug is enhanced by storing in MDIs and DPIs since the drug is not comes in contact atmospheric oxygen and moisture. The drug can be directly applied to the affected areas. Administration of drug by aerosol is a rapid process.

Which of the following is used in aerosols?

CFC is used in aerosols.

What are aerosol give example?

An aerosol is a collection of solid particles or liquid droplets dispersed in air. Examples include smoke, fog, sea spray and pollution particles from vehicles. Particle sizes can range from the nanometre (a millionth of a millimetre) to the millimetre scale.

What are aerosols give examples Class 9?

An aerosol is a colloid of fine solid particles or liquid droplets, in the air or another gas. Examples of natural aerosols are fog, geyser steam.

What type of waste is aerosol?

hazardous wastes
Aerosol cans may be hazardous wastes when they are non-empty and will no longer be used. Aerosol cans are not hazardous wastes when they have been emptied of contents.

What are aerosol treatments?

Aerosolized medications treat a variety of respiratory diseases, including respiratory infections. They are typically administered to patients using a nebulizer or other type of aerosol generator, such as a metered dose inhaler. Occupational exposure to aerosols may occur during treatments.

What is an aerosol in medicine?

Aerosol: A fine spray or mist. Medications in aerosol form can be administered via a nebulizer and inhaled.

What is aerosol mask?

An aerosol (AIR o sol) is a mist that has medicine in it. Aerosols help make breathing problems better. Your child breathes it into the lungs through a mask or mouthpiece (Picture 1). The effect of the aerosol depends on the type of medicine used.

Is aerosol solid or liquid?

Aerosols are extremely small solid particles, or very small liquid droplets, suspended in the atmosphere. Aerosols consisting of solid particles can be placed in the atmosphere primarily by large dust storms, volcanic eruptions, or the soot particles from large fires.

What are two natural causes of aerosols?

Sea salt and dust are two of the most abundant aerosols, as sandstorms whip small pieces of mineral dust from deserts into the atmosphere and wind-driven spray from ocean waves flings sea salt aloft. Both tend to be larger particles than their human-made counterparts.

How do aerosols affect human health?

On balance, aerosol particles tend to scatter energy back to space and cool the planet. This tends to offset the warming associated with greenhouse gases. Aerosols also can adversely affect human health.

How do aerosols affect the environment?

Aerosols and Clouds (Indirect Effects) Whereas aerosols can influence climate by scattering light and changing Earth’s reflectivity, they can also alter the climate via clouds. On a global scale, these aerosol “indirect effects” typically work in opposition to greenhouse gases and cause cooling.

Do aerosols cool or warm the atmosphere?

Aerosols cool the earth’s surface but warm the atmosphere. ew research based upon NASA satellite data and a multinational field experiment shows that black carbon aerosol pollution produced by humans can impact global climate, as well as seasonal cycles of rainfall.
