What two elements are liquids at room temperature?
Liquids around room temperature. The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.

Which alkene is liquid at room temperature?
At room temperature, ethene, propene and butene are gaseous while higher, unbranched alkenes are liquids. Starting with 16 C atoms, alkenes are solids.
Which of the following is a liquid form of aerosol?
Answer: (3) Mist Fume, Dust and Smoke are a solid form of aerosol. Liquid aerosol involves liquid dispersed in gas.
What is the example of aerosol?
What are aerosols? 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.
Is smoke an aerosol?
An aerosol is a suspension of fine solid particles and/or liquid droplets in a gas (usually air). Cigarettes generate a smoke aerosol that is the result of the combustion (burning) of tobacco, and contains carbon-based solid particles. While smoke is an aerosol, not all aerosols are smoke.
What is the meaning of aerosols?
aero-solution
What is the use of aerosol?
In addition, aerosols are used in healthcare as disinfectants, inhalers, anesthetic preparations, etc. Household preparations in aerosol cans include air fresheners, cleaning agents, car cosmetics, paints and varnishes, etc. Last but not least, certain foodstuffs, such as oil or whipped cream.
What is wrong with aerosols?
Every time you spritz an aerosol, you raise your carbon footprint because they contain hydrocarbon and compressed gasses. In fact, today’s CFC-free aerosols also emit VOCs that contribute to ground-level ozone levels, a key cog in asthma-inducing smog.

What causes aerosols?
Although light can be scattered in any direction, some of the sun’s light is scattered away from the earth’s surface by aerosol particles in our atmosphere, which is what causes the direct aerosol effect. Indirect aerosol effects are related to how aerosols affect clouds.
How are aerosols formed?
Tiny airborne particles, also called aerosols, are formed in several different ways. They can be created by sea salt from sea spray and bursting bubbles, windblown dust, and volcanic eruptions as well as from fossil fuel combustion from automobiles, ships, airplanes, and factory emissions.
How do aerosols affect climate?
Aerosols influence climate in two primary ways: by changing the amount of heat that gets in or out of the atmosphere, or by affecting the way clouds form. Aerosols also influence how clouds form and grow. Water droplets coalesce readily around particles, so a particle-rich atmosphere promotes cloud formation.
Are aerosols safe?
As long as the can and the dispensing device remain intact, aerosol cans are safe. But any number of problems, such as a puncture, a faulty valve, excessive temperatures, or corrosion can result in unintended depressurization.
How do aerosols affect air quality?
The aerosols that are from air pollution are hazardous to human health. When the little particles get deep into a person’s lungs it can make him or her very ill. Aerosols can also limit visibility, causing haze in many parts of the world.
