A substance has a melting point of 14c and a boiling point of 78c in what state is the substance at 78c?

The substance would be in a liquid and gas state, this would be due to vaporization that is happening during boiling.

What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
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.
Is the boiling point of a substance a physicsl property?
No, the boiling point is a physical property because the compound or substance is not changing chemically (only physically from a liquid to a gas). The boiling point is considered the temperature at which the vapor pressure of the liquid equals the atmospheric pressure surrounding the liquid. All of these are physical properties, making the boiling point a physical property too.
What state would melting and boiling point be st 1000 degrees celsius?
Melting and boiling point of what? Stop being stupid
What physical property dose not identify a substance?
boiling point --------- Boiling point is a specific characteristic of a substance or element; the mechanical strength, the viscosity, the electrical resistivity are more difficult to be used for a sure identification of a substance.
Is a characteristic a boiling point?
A characteristic for the boiling point is that the substance start changing state.
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 do boiling point and melting point have to do with the phase of matter of an element at room temperature?
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.
How do you identify the change of state a substance is undergoing?
through it's boiling, melting, and freezing point.
What is the physical state of substance with a melting point of 13 degree celsius and boiling point of 60 degree celsius?
liquid
What will be the state of melting point and boiling point of petrol?
Melting point it would liquefy, boiling point it would vaporize.
Are melting and boiling points of a substance the same?
The melting and boiling points of a substance (in this case I am assuming you are referring to a pure substance, and not a mixture), are the same. The triple point is defined by the temperature and pressure at which solid, liquid, and vapor of a substance, can coexist in equilibrium. At any pressure below the triple point, only sublimation and condensation are possible (no liquid phase is possible). Between the triple point pressure and the critical point pressure, there is a difference between the melting and boiling points, of a substance. The melting point temperature will be lower than the boiling point. At the critical point, the densities of the liquid and vapor phases, have merged, and boiling no longer occurs. At and above the critical point, you cease to get liquid and vapor, but you get what is referred to as a "supercritical fluid".
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 is the substance of boiling point?
The boiling point of a substance is the temperature at which it changes from liquid state to gaseous or vapor state.
Is the boiling point of a substance a physicsl property?
No, the boiling point is a physical property because the compound or substance is not changing chemically (only physically from a liquid to a gas). The boiling point is considered the temperature at which the vapor pressure of the liquid equals the atmospheric pressure surrounding the liquid. All of these are physical properties, making the boiling point a physical property too.
Short difference between melting and boiling point?
Boiling point is the temperature at which a liquid is in equilibrium with the gas phase of the same liquid. Melting point is the temperature at which a solid becomes a liquid (i.e. the point at which a solid and liquid of the same substance will be in equilibrium)
What state would melting and boiling point be st 1000 degrees celsius?
Melting and boiling point of what? Stop being stupid
How is the melting point of a substance related to its freezing point?
The melting point of a substance is when a substance turns from a solid to a liquid, and the freezing point is when a substance turns froma liquid to a sold. This of water, t he freezing point, when it turns to a solid (ice) is 0 degrees C. Hope that helps!
