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.

What is the boiling point of matter?
When a substance is heated to its boiling point, the liquid begins to turn into a vapor. Thus, both phases of matter (liquid and vapor) will be present. Boiling point is the temperature at which atmospheric pressure equals the vapor pressure of the liquid. For this reason, the liquid is able to be released into the atmosphere as a gas.
What state of matter is calcium in at atmospheric pressure?
Calcium is a solid at atmospheric presure up to the melting point of 842 0C.
What are the factors that affect changes in matter?
Pressure and temperature are two factors that both affect the state of any type of matter.
Why might the typical boiling point change?
Due to the temperature, environment, and matter the boiling pot will change. Hope this will help By either the pressure or purity of the substance.
Would you expect the boiling point of water in Baguio city be higher or lower that 100 degree Celsius why?
This has been asked over and over recently. Is this part of an exam or a class? Boiling point decreases with altitude because there is less pressure. The water will boil when the vapor pressure equals the air pressure. Baguio city is about 1500-1600 meters above sea level, making its temperatures roughly 8 degrees C less than the sea level areas of the Phillipines. For every 1000 feet in elevation, the boiling point of water decreases about 1 degree C. Very roughly, Baguio city is at 4500 feet elevation. The boiling point of water at Baguio city should be about 4.5 degrees C less than 100 degrees C, or 95.5 degrees C.
What is boiling in matter?
Phase shift from liquid to gas (vapor), where the vapor pressure is just equal to the atmospheric pressure.
How can I define boiling point scientifically?
Boiling point is defined as the temperature at which the vapour pressure of a liquid is equal to the atmospheric pressure. In other words, it is the minimum temperature at which a matter which is in the liquid state gets converted to a matter in the gaseous or vapour state.
What is the property of matter that is dependent to altitude?
The property of matter that is dependent on altitude is atmospheric pressure. Atmospheric pressure decreases with increasing altitude due to the decrease in the weight of the air above. This decrease in pressure affects various aspects of the environment, such as boiling points of liquids and gas behavior.
What is the boiling point of matter?
When a substance is heated to its boiling point, the liquid begins to turn into a vapor. Thus, both phases of matter (liquid and vapor) will be present. Boiling point is the temperature at which atmospheric pressure equals the vapor pressure of the liquid. For this reason, the liquid is able to be released into the atmosphere as a gas.
Is the phase of matter which is exposed to normal atmospheric pressure solely dependent upon temperature?
Yes. The phase of matter which is exposed to normal atmospheric pressure solely dependent upon temperature.
What state of matter is calcium in at atmospheric pressure?
Calcium is a solid at atmospheric presure up to the melting point of 842 0C.
In what state of matter does a diamond exist at atmospheric pressure?
the STD of a diamond is Solid
What is the state of matter of mercury in liquid?
berometers measure atmospheric pressure.
How does thermal energy affect matter?
It increases temperature of the matter leading to melting, boiling and subsequent vaporization of the matter.
The phase of matter which is exposed to normal atmospheric pressure is solely dependent upon?
Temperature
What is the temperature at a liquid changes into a solid?
It depends what type of matter it is, as well as, atmospheric pressure.
Why do you not notice atmospheric pressure on your body?
We do not feel the atmospheric pressure - roughly 101kPa - because our bodies have adapted to it, to the point where the pressure in our bodies exactly balances the external pressure, resulting in no net force on your body.
