Phenol has a vapor pressure despite being a solid at room temperature because it can sublimate, meaning it can transition directly from a solid to a gas without becoming a liquid. This occurs due to the presence of weak intermolecular forces, such as hydrogen bonding, which allows some phenol molecules at the surface to escape into the vapor phase. Additionally, even solid substances can exhibit vapor pressure if their molecules have sufficient energy to overcome the attractive forces holding them in the solid state.
What else can I help you with?
What would have more vapour pressure pure ice or sweet ice?
Both will have same vapour pressure as salt{NACL} would get trapped in ice and in solid iced state get seprated from pure ice crystals. so in case melting of ice in soln state pure water will have more vapour pressure but in solid state both will have same vapour pressure.
What is the difference between gas and vapours?
Gas refers to substances that are in a gaseous state at room temperature and pressure, whereas vapour refers to the gaseous state of a substance that is usually a liquid or solid at room temperature and pressure. Vapour is produced by evaporation or boiling, while gas exists as a gas naturally.
Which has more energy vapor or solid?
vapour
The Pressure of Earth's layers causes the inner core to be?
solid due to extreme pressure, even though it is composed of mostly iron and nickel.
What can be a liquid solid and gases?
Water - water, ice and steam/vapour
Is phenol a solid or liquid?
Phenol is a viscous liquid or can be crystals as phenol has a melting point of 40.5°C which would make it a solid at room temperature.
What is pressure vapour?
Vapour pressure is the pressure of the steam of a substance at a certain temperature. This does not automatically mean that the substance is completely evaporated. When the vapour pressure reaches the surrounding (atmospheric) pressure, the substance starts to boil or sublimate. Also at very low temperatures, even when the substance is in solid state, a certain amount of substance already exists as vapour. Though, for the most substances, the proportion of vapour is very small compared to the solid portion. Finally, a substance does not have to melt before it evaporates. This is called sublimation and occurs, e.g., when solid carbon dioxide (dry ice) is used: It will evaporate directly from the solid state (under normal ambient physical conditions), because, with rising temperature, the vapour pressure is already exceeding the atmospheric pressure before the melting point is reached.

What state is phenol at room temperature?
Though butanol may refer to any of 4 different compounds (depending on the placement of the alcohol group), all are liquids are room temperature.
What is phenol's state at 25 degrees Celsius?
Phenol is a solid at 25 degrees Celsius.
What is the state of phenol at 25 C degrees?
Phenol is a solid at room temperature (25°C). It has a melting point of 40.5°C, so at 25°C, it would exist in a solid state.
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
What is the antonym for vapour?
The antonym for vapor is solid.
Is vapour a solid liquid or a gas?
As the word "vapour" indicates, it is a gas.
What do you call when solid is changed into gas?
sublimation. for example when camphor is heated at atmospheric pressure it will not melt but get sublimed into vapour phase. similarly it is possible to sublime ice into water vapour without converting into liquid-water by applying very low pressure.
What effect do you think that has no air pressure on the ground?
Without atmospheric pressure, water will boil to vapour, so as our blood and body would explode. Pressure is what that keep water in liquid and solid state on earth.
The substance which changes from solid to vapour state at normal atmospheric pressure without being liquified is?
One substance that does that is carbon dioxide.
