Does boiling point and melting point occur at the same temperature?
It depends on the substance and the pressure. For most substances at atmospheric pressure, the boiling point is much higher than the melting point. However, some things, like nitrogen and carbon dioxide, do not have any liquid phase at atmospheric pressure--they go directly from solid to gas and vice-versa.
A substance change from a solid to a liquid at its?
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
What will determine if the substance is a solid liquid or gas at 100 degrees?
The state of a substance at 100 degrees Celsius is primarily determined by its boiling point. If the boiling point is above 100 degrees, the substance will be a solid or liquid; if it is below 100 degrees, it will be a gas. Additionally, atmospheric pressure can influence the boiling point, meaning that at higher pressures, substances may remain in a liquid state at temperatures above their standard boiling points. Thus, both the intrinsic properties of the substance and the external conditions play crucial roles.
Explain with an example how melting and boiling points are same?
Melting and boiling points are the same for a substance at its triple point, where all three phases (solid, liquid, gas) can coexist in equilibrium. For example, water has a melting point of 0°C and a boiling point of 100°C at standard atmospheric pressure, but at its triple point, water can exist in all three phases at 0.01°C and 611.657 pascals of pressure.
Is boiling temperature a characteristic property?
Yes, boiling point is a characteristic property of matter. It is called a characteristic property because no matter how much of a pure substance you have, the boiling point should remain the same. Therefore, it is a characteristic property of pure substances.
What are the effects of pressure on melting boiling points of a substance?
Increasing pressure generally increases the melting and boiling points of a substance. This is because pressure forces molecules to be packed closer together, making it harder for them to break free from each other in the solid or liquid phase. Conversely, decreasing pressure lowers the melting and boiling points.
How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.

However, some things, like nitrogen and carbon dioxide, do not have any liquid phase at atmospheric pressure--they go directly from solid to gas and vice-versa.
Is the boiling point of something the same as the melting point?
The boiling point is the temperature at which the vapor pressure of the liquid is equal to the external pressure. It is also the condensation point. The freezing point is the temperature at which liquid and solid coexist in equilibrium. It is also the melting point.
A substance change from a solid to a liquid at its?
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
Temperature at which a substance changes from a solid to a gas is?
boiling point
Why are the melting point and boiling point of the same matter different?
Boiling point is the temperature at which a substance turns into a gas, while melting point is the temperature at which a substance turns into a liquid state from a solid state. The boiling point is always a higher temperature then the melting point. The melting point has a substance turn into a liquid from solid, and boiling point has a liquid turn into a gas.
What will determine if the substance is a solid liquid or gas at 100 degrees?
The state of a substance at 100 degrees Celsius is primarily determined by its boiling point. If the boiling point is above 100 degrees, the substance will be a solid or liquid; if it is below 100 degrees, it will be a gas.

If a substance is kept at atmospheric pressure what is its phase of matter completely depend on?
The phase of matter a substance is in at atmospheric pressure is primarily dependent on its temperature. At a certain temperature, known as its boiling point, a substance will transition from a liquid to a gas. Conversely, at another temperature, known as its freezing point, a substance will transition from a liquid to a solid.
What change of state occurs when a substance reaches it's melting point. What occurs when it reaches it's boiling point?
When a substance reaches its melting point it changes from solid to liquid. When a substance reaches its boiling point it changes from liquid to gas.
What is the temperature of a substance when it turns into another state of matter?
The temperature at which a substance changes state is called its melting point or boiling point, depending on the transition. For example, when a solid turns into a liquid, it reaches its melting point; when a liquid turns into a gas, it reaches its boiling point.
