Boiling point
boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature.
Freezing point
Freezing point is the temperature at which a liquid becomes a solid at normal atmospheric pressure. Alternatively, a melting point is the temperature at which a solid becomes a liquid at normal atmospheric pressure
Condensation point
Condensation point is a temperature at which gas changes to liquid. Generally, boiling point is same as condensation point. For water boiling point is 100∘C, -212∘F. So, condensation point is also 212∘F.
Melting point
Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change
Explanation:
Explain Boiling point
The boiling point of a liquid is the temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure of the liquid’s environment. At this temperature, the liquid is converted into a vapour.
The boiling point of the liquid depends upon the pressure of the surrounding.
When the liquid is at high pressure, it has a higher boiling point than the boiling point at normal atmospheric pressure.
The boiling point of different liquids is different for a given pressure.
Explain Freezing point
Freezing refers to the phase change of a substance from the liquid state to a solid-state. This is a phase change phenomenon which means that a substance is transformed from one state of matter to another state.
The level a liquid is freezing at is its freezing point.
During higher temperatures, molecules with stronger intermolecular forces are closely drawn together to form a solid, and their freezing point is higher. Until the temperature is reduced, molecules with lower intermolecular forces will not solidify.
Explain Condensation point
Condensation is the process by which water vapour in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapour
Condensation is the slowing down of a gas’s molecules as they join together to create a liquid. When gas molecules transfer their energy to something colder, they slow down and become attracted to one another, forming a liquid. The rate of condensation is increased when water vapour is made colder.
Explain Melting point
The melting point is usually defined as the point at which materials changes from a solid to a liquid.
The temperature at which solid changes its state to liquid at atmospheric pressure is called the melting point of that liquid.
This is the point at which both liquid and solid phase exists at equilibrium.
The melting point of the substance also varies with pressure and is specified at standard pressure.
