What does volatility mean in chemistry?
definition.Volatility Description The ease with which the substance evaporates (turns into a gas or vapor). Volatile substances can be defined as (1) substances that evaporate readily at ambient temperature and/or (2) substances that have a measurable vapor pressure. The term volatile is usually applied to liquids.
What chemistry does low volatility mean?
In chemistry, volatility is a material quality that describes how easily a substance evaporates. At a given temperature and pressure, substances with high volatility are more likely to exist as vapors, while substances with low volatility are more likely to exist as vapors. more likely to be liquid or solid.
What is the volatility of water?
Water (H2O) is medium volatility. It has a boiling point of 100oC and evaporates only slowly at room temperature. It is not flammable or explosive.
How do you calculate volatility in chemistry?
Scientists often use the boiling point of a liquid as a measure of volatility.
- Volatile liquids have low boiling points.
- A liquid with a low boiling point will start to boil faster than a liquid with a high boiling point.
What Causes Highly Volatile Chemicals?
The volatility of organic chemicals is directly related to vapor pressure of organic chemicals. At a given temperature, an organic chemical with a higher vapor pressure evaporates (volatizes) more easily than an organic chemical with a lower vapor pressure.
