Vapor pressure describes the tendency for a substance to vaporize. It is determined by the strength of the intermolecular forces present with in the substance and the substance's temperature. Answer and Explanation: A liquid boils when its ...
A liquid boils when its A) temperature is equal to 273 K (standard temperature). B) vapor pressure is equal to, or greater than, the external pressure pushing on it. C) temperature is greater th What would be the effect of either increasing...
When the temperature of a liquid is raised enough, the liquid boils. This means that bubbles of vapor, containing millions of molecules, form below the surface. In order for such bubbles to be produced, the pressure of the vapor inside them must be equal to the pressure of the air upon ...
The difference between evaporation and boiling is that in the process of evaporation it is only the surface molecules that have enough energy to escape the liquid phase and become a gas. When a liquid boils, on the other hand, the molecules below the surface have enough energy to escape the...
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid is equal to View Solution A liquid boils when its vapour pressure equals View Solution Assertion : The normal boiling point of water is 100 C^(@) and standard boiling point of water is 99.6 C^(...
azimuthal quantum number- the quantum number associated with the angular momentum of an electron, determining the shape of its orbital. B Definitions - Background Radiation to Buffer Boiling occurs when the vapor pressure of a liquid exceeds atmospheric pressure.David Murray and Jules Selmes / Getty...
In addition, when investigating processes occurring when liquid helium boils in a centrifugal force field, its thermodynamic parameters may be close to the critical values, and the dependences of the thermophysical properties of the liquid and vapor on the temperature and pressure must be taken into...
Ethanol boils at 78.4 °C, water boils at 100 °C, but the azeotrope boils at 78.2 °C, which is lower than either of its constituents. Indeed 78.2 °C is the minimum temperature at which ethanol–water solution can boil. When an azeotrope is partially boiled, the resulting vapor has ...
The solution when boils heat up to form a vapor. The vapor formed from the solution exerts pressure on the liquid surface from both sides of the liquid boundary. The pressure exerted by vapors is called vapor pressure.Answer and Explanation: The vapor pressure of a liquid when...
Generally, the vapor pressure of a liquid is related to: amount of the liquid, atmospheric pressure, temperature, intermolecular forces How does temperature affect a liquid's intermolecular forces? What is the relationship between the vapor pressure of a liquid ...
