Boiling and vaporization are two different scientific phenomena. Vaporization of a compound or even an element is basically a phase where the transformation of vapor and water takes place while boiling is a bulk phenomenon.
Boiling is a rapid and fast vaporization of a liquid when it is heated at its boiling point, and boiling point is a temperature at which the pressure of the vapor on liquid is equal to the pressure that is exerted on the liquid by the atmosphere that is surrounding it.
Boiling vs Vaporization
The main difference between boiling and vaporization is that vaporization takes place at all the temperatures when any compound or element is heated, while boiling takes place at a particular temperature only that is known as boiling point. Vaporization takes place from the surface only, but when boiling, the entire liquid is heated and boiled.
Boiling is a rapid and fast vaporization of a liquid when it is heated at its boiling point, and boiling point is a temperature at which the pressure of the vapor on liquid is equal to the pressure that is exerted on the liquid by the atmosphere that is surrounding it.
Vaporization is simple words, is a process of conversion of a substance from its liquid or solid form into the gaseous form. While the direct conversion of a substance from a solid state to a gaseous state is known as sublimation.
Comparison Table Between Boiling and Vaporization
| Parameters of Comparison | Boiling | Vaporization |
| Meaning | Boiling is a rapid and fast vaporization of a liquid when it is heated at its boiling point. | Vaporization is a process of converting a substance from its liquid or solid form into a gaseous form. |
| Source of energy | For boiling substance energy from an external source is required. | But for vaporization, can take place while using an internal source. |
| Temperature | Boiling requires a specific temperature for heating a substance whether it is solid or liquid. | Vaporization does not require a particular temperature and can take place at any point. |
| Time and period | Boiling occurs very rapidly and is a fast process. | Vaporization is quite a slow process. |
| Bubble formation | Bubble formation takes place while boiling a substance. | No bubble is formed during vaporization. |
What is Boiling?
Boiling is basically the rapid vaporization of a liquid that happened when the liquid substance is heated to its boiling point. The boiling of a solid substance is called sublimation.
The boiling point of a substance is the temperature at which the substance starts getting heated and changing into gaseous form. The boiling point of water is 100-degree Celsius or 212-degree Fahrenheit. These boiling points at higher degrees of altitude are comparatively lower because of decreased pressure of the atmosphere there.
Boiling the water is a process of making the water potable so that if there are any microbes or viruses are present in it, they are killed. Although, the sensitivity of every other microbe varies in the case of heat. But most of the viruses or microbes present in the water are killed when water is held at 100 degrees Celsius of temperature, as ten minutes of the temperature of 70 degrees Celsius is enough for most of the bacteria and viruses.
What is Vaporization?
Vaporization, in simple words, is a process of conversion of a substance from its liquid or solid form into the gaseous form. While the direct conversion of a substance from a solid-state to a gaseous state is known as sublimation.
Boiling and evaporation are the two types of vaporization. During vaporization, when the temperature increases, following its result, the kinetic energy that is present in the molecules of the substances releases. Now because of this release of kinetic energy, the force of attraction that is in the molecules that bind them is reduced and then released eventually. And thus, as a result, all the molecules escape into their surrounding in the gaseous form of vapors.
There is a total of four factors that affect the rate of vaporization- temperature, the surface area of the substance, pressure, and wind speed.
Main Differences Between Boiling and Vaporization
- The main difference between boiling and vaporization is that Vaporization takes place at all the temperatures when any compound or element is heated, while boiling takes place at a particular temperature only that is known as boiling point.
- Vaporization of a compound or even an element is basically a phase where the transformation of vapor and water takes place while boiling is a bulk phenomenon.
- Bubble formation takes place while boiling a substance, but in vaporization, no bubble formation takes place.
- During boiling, the liquid substance is converted into gaseous directly, but in vaporization, there is a state of matter basically from solid or liquid to gaseous form.
- During boiling, only top-level of water turns into gas, but in vaporization, all the water present to be vaporized turns into gas.
- Boiling occurs very rapidly and is a fast process, but Vaporization is quite a slow process.
Conclusion
From the discussion so far, it is to be concluded that boiling is basically a type of vaporization. Boiling is a rapid and fast vaporization of a liquid when it is heated at its boiling point, and boiling point is a temperature at which the pressure of the vapor on liquid is equal to the pressure that is exerted on the liquid by the atmosphere that is surrounding it. Vaporization is that Vaporization takes place at all the temperature when any compound or element is heated while boiling takes place at a particular temperature only that is known as boiling point.
Vaporization takes place at all the temperatures when any compound or element is heated, while boiling takes place at a particular temperature only that is known as boiling point. Vaporization takes place from the surface only while when boiling, the entire liquid is heated and boiled.
