Why do different solids and liquids have definite boiling and melting point?
Answers
Answer:
hey mate
Explanation:
ur ans gonna be....the brief reason is here...
In a solid, as the molecules vibrate more strongly, at some temperature they will have enough speed and energy to break from the rigid structure and move around past each other. This is when they become a liquid.
So the melting point is the temperature at which molecules in a solid can move past each other and form a liquid.
The boiling point, on the other hand, involves liquids and gases. As liquid molecules are moving around, some molecules at the surface of the liquid are escaping. They don’t get very far because of air at the top that pushes the molecules back into the liquid.
As temperature is increased, the liquid molecules move faster and faster and more of them escape as gas. The boiling point is the temperature at which the gas from the liquid is pushing the air with the same force the air is pushing back.
different solids and liquids have definite boiling and melting point due to the presence of the structure which is present in their molecule.
Explanation:
- the boiling point and the melting point is determined by the temperature in which there is separation of the molecules of the substance or there is green in the kinetic energy.
- As a result of this depends on the characteristics of the molecule which forms the substance. In addition to this a large number of substances have certain hydrogen bond with adds to the boiling and melting point of the substance.
