A volatile substance is one that evaporates or sublimates at room temperature or below. Volatile substances have higher vapor pressures versus non-volatile substances at the same temperature. Examples of volatile substances include alcohol, mercury, and gasoline.

What is volatile and non volatile substance?
1. Volatile substances have a tendency to vaporize whereas nonvolatile substances do not have a tendency to vaporize. 2. Volatile substances have a high vapor pressure at normal room temperature and pressure. Nonvolatile substances do not have a high vapor pressure in these conditions.
What is the most volatile substance?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state.
What makes a chemical volatile?
Volatility is indicated by a substance’s vapor pressure. It is a tendency of a substance to vaporize or the speed at which it vaporizes. Substances with higher vapor pressure will vaporize more readily at a given temperature than substances with lower vapor pressure.
What is volatile substance Short answer?
The term ‘volatile substances’ refers to gases or chemicals that evaporate at room temperature to form a vapour which can be inhaled. They are found in a whole range of legal, household products.
Is water a volatile substance?
Water (H2O) is moderately volatile. It has a boiling point of 100oC and evaporates only slowly at room temperature.
What is example of a volatile liquid?
These liquids have a measurable vapour pressure. The examples of volatile liquids are – acetone, alcohol, petrol, ether gasoline, butyl acetate etc., Hope you get it.
Is Sugar volatile?
At high temperatures, however, the sugar itself can be set ablaze. Extreme heat forces sucrose to decompose and form a volatile chemical called hydroxymethylfurfural, which easily ignites and sets the rest of the sugar on fire.
Which is a volatile liquid?
A liquid that evaporates readily at normal temperature is known as a volatile liquid. Volatile liquids are liquids that transform easily into the vapor phase. Usually, the vapor pressure of volatile liquids is very high.
Why is alcohol volatile?
Alcohol is more volatile than water, because its vapour pressure is 2.5 times greater than water. A liquid vaporises when its vapour pressure become equal to atmosphere pressure.
Is alcohol a volatile liquid?
A highly volatile substance such as rubbing alcohol (isopropyl alcohol) will quickly evaporate, while a substance with low volatility such as vegetable oil will remain condensed. In general, solids are much less volatile than liquids, but there are some exceptions.
Is petrol a volatile liquid?
gasoline, also spelled gasolene, also called gas or petrol, mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. It is also used as a solvent for oils and fats.
What is a volatile substance class 9?
1 Answers. A volatile substance is is the one which can easily evaporate at room temperature. In general, any substance with a boiling point below 100 degrees Celsius is considered volatile, while all other liquids are called nonvolatile. For example, methanol, acetonitrile, etc are volatile substances.
What are non volatile substances?
What Does Nonvolatile Mean? Nonvolatile is the inability of a substance to readily evaporate into gas. Nonvolatile substances are usually solids with boiling points above 212ยฐF (100ยฐC), and do not vaporize easily at room temperature and pressure.
Is salt non volatile?
Sugar (sucrose) and salt (sodium chloride) are nonvolatile solids. It’s probably easier to imagine a nonvolatile substance if you consider the properties of materials that are volatile. Examples include alcohol, mercury, gasoline, and perfume. Volatile substances readily release their molecules into the air.
Is Sand volatile?
Material such as sand, salt, iron, calcium, and other mineral materials that are only slightly affected by the actions of organisms and are not lost on ignition of the dry solids at 1,022ยฐF (550ยฐC). Volatile materials are chemical substances usually of animal or plant origin.
Is honey volatile?
The chemical families into which the volatile compounds in honey belong include: hydrocarbon; aldehyde; alcohol; ketone; acid; ester; benzene and its derivatives, furan and pyran; norisoprenoids; terpenes and its derivatives and sulphur; and cyclic compounds [15].
What is volatile salt?
a solution of ammonium carbonate in alcohol and aqueous ammonia, often containing aromatic oils, used as smelling salts.
Is ethanol volatile?
Ethanol, C2H5OH, is a colorless volatile flammable liquid synthesized by fermentation of sugars and starches. It is widely used as a solvent and in drugs, cleaning solutions, etc. Ethanol, CH3CH2OH, is a colorless liquid with distinctive taste and odor.
Is water a non-volatile solvent?
Water having a boiling point of 100 ฬC, is a fine example of a non-volatile liquid. As discussed earlier, this is due to the presence of strong hydrogen bonds between water molecules. Mercury is also a non-volatile liquid.
What is non-volatile solvent?
Non-volatile solvent means any solvent used in the extraction process that is not a volatile solvent as defined by state law. For purposes of this chapter, a non-volatile solvent includes carbon dioxide (CO2) used for extraction and ethanol used for extraction or post-extraction processing.
Why is water not volatile?
Some compounds, such as water, are extremely non-volatile; often this is because of strong chemical bonds between the moleculesโthe most common of which are hydrogen bondsโthat resist the tendencies of individual molecules to enter the gaseous state.
Why is volatile?
Volatile is usually applied to a variable when we are declaring it. The main reason behind using volatile keyword is that it is used to prevent optimizations on objects in our source code. Therefore, an object declared as volatile can’t be optimized because its value can be easily changed by the code.
Is vinegar volatile?
The main volatile compound in vinegar is acetic acid, which gives vinegar its strong, sour aroma and flavour. Other volatile compounds present in vinegars are mainly alcohols, acids, esters, aldehydes and ketones.
Which is least volatile?
Hence, the least volatile liquid among the four is water.
