The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
It means that the freezing or melting points do not change, that they are always the same, depending on the type of matter. For eg. the melting point or freezing point of water is 0○ Celsius and the boiling point is always 100○C.
it changes depending upon the temperature
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.
The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid. These properties are unique to each substance and can be used to identify or characterize them.

A melting point is the temperature at which a substance changes from a solid to a liquid state, while a boiling point is the temperature at which a substance changes from a liquid to a gas. Both melting and boiling points are characteristic physical properties of a substance and can be used to identify and classify materials.
At the melting point, the temperature remains constant because the energy being absorbed is utilized to overcome the intermolecular forces holding the solid together, rather than increasing the temperature. Similarly, at the boiling point, the temperature remains constant as the energy is used to break the intermolecular bonds holding the liquid together, allowing the substance to transition into the gas phase.
The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
It means that the freezing or melting points do not change, that they are always the same, depending on the type of matter. For eg. the melting point or freezing point of water is 0○ Celsius and the boiling point is always 100○C.
it changes depending upon the temperature
The temperature at which the particles of a substance have enough kinetic energy to transform from one phase to another is called the phase transition temperature. This temperature varies depending on the substance and the phase transition, such as melting, boiling, or freezing.
Every substance has its own unique melting point and boiling point. The melting point is the temperature at which a solid substance changes into a liquid, while the boiling point is the temperature at which a liquid changes into a gas. These physical properties are characteristic of each substance and can be used to identify and distinguish between different materials.
The substance has a melting point of 50°C and a boiling point of 200°C. This information can help identify the substance by comparing it to known melting and boiling points of different substances. The melting point indicates the temperature at which the substance transitions from solid to liquid, while the boiling point is the temperature at which it transitions from liquid to gas.
