Boiling

What is boiling?

Boiling is the process by which an element is transformed from a liquid state to a gaseous state through exposure to high temperatures. In this sense, the molecules that make it up reach a temperature such that they spontaneously transform into a gaseous state.

The boiling process is generated spontaneously and naturally to the extent that external agents allow it to carry out this action. It should be noted that boiling is a process opposite to the condensation process.

Boiling characteristics

  • Physical process.
  • By subjecting it to high temperatures, it achieves the transformation.
  • The process arises spontaneously.
  • They originate through the change from liquid to gaseous state.
  • Molecules collide with each other.
  • In the boiling process, the molecules stir much faster.
  • The molecules escape out of the same mass into the atmosphere and become a gaseous state.

Boiling point

The boiling begins when the heating a liquid, gas bubbles appear throughout its mass. This occurs at a fixed temperature for each substance.

The boiling point of a substance is the temperature at which the substance boils . At the microscopic level it happens that almost all the particles have enough energy to escape from the liquid and be released in the form of gas.

Difference with evaporation

Both processes are responsible for transforming the state of matter from liquid to gaseous. This process is known as vaporization.

The difference in both lies in the way in which matter is transformed, since this change from a liquid to a gaseous state is completely different. In the boiling process , the change occurs in the entire mass of matter, while in the evaporation process the process is observed only on the surface of the fluid.
