The boiling point temperature of a compound increases as the pressure increases,
until the pressure reaches the critical pressure of the compound. For water, you have :
P ( kPa ) T ( C )
------------ ----------
1.0.............. 6.97
50....... .......81.32
100............ 99.61
101.325... 100.0
500........... 151.83
8000......... 295.01
20000....... 365.75
22064....... 373.95 ( Critical Point of H2O )

Is boiling point a physical or chemical property?
It is a physical property because the element/compound will change without involving a change in chemical composition.Physical
What can be said of a boiling point of a liquid?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
How does the boiling point of a liquid vary with pressure?
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.
How does pressure and impurities affects boiling point?
Boiling is used to describe a change of state of a pure liquid to vapour phase. The particular temperature at which this change of state occurs is defined as the boiling point of that specific liquid. Now the question is will addition of impurities have any effect on the boiling point of water. The addition of impurities such as salt or sugar to pure water raises its boiling point.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
Can boiling temperature of an element change?
The boiling temperature of an element can change by changing the pressure.
What is Description of change of boiling?
The change of boiling refers to the transition of a substance from liquid to gas at its boiling point, where the vapor pressure equals atmospheric pressure. During this process, heat energy is absorbed, enabling molecules to overcome intermolecular forces and escape into the gaseous phase. Boiling occurs uniformly throughout the liquid, resulting in the formation of bubbles that rise to the surface. Factors such as atmospheric pressure and impurities can affect the boiling point and the boiling process itself.
What two factors affect the boiling point of water apex?
The two main factors that affect the boiling point of water are the atmospheric pressure and the presence of impurities in the water. As atmospheric pressure increases, the boiling point of water also increases. Impurities in water, such as salt, can raise the boiling point of water due to the change in the composition of the solution.
Is boiling point a physical or chemical property?
It is a physical property because the element/compound will change without involving a change in chemical composition.Physical
What physical effect can change the boiling of substance?
Pressure
How does the liquid know the pressure of the atmosphere?
The boiling point of an element or a substance is the temperature at which the Vapor_pressureof the liquid equals the environmental pressure surrounding the liquid.if we close the container and change the pressure outside the container.. the boiling point will change... why?? how will the solution inside know that the pressure outside the container is changing and it has to now change its boiling point.??
How can you change the boiling point of liquid?
You can change the boiling point of a liquid by adjusting the pressure on the liquid. Increasing the pressure raises the boiling point, while decreasing the pressure lowers it. This is why water boils at a lower temperature at higher altitudes where the atmospheric pressure is lower.
Will this affect the temperature of the liquid left in the container?
Yes, the change in pressure could affect the temperature of the liquid left in the container. When pressure decreases, the liquid's boiling point also decreases, potentially causing it to evaporate or cool down.
Does waters boiling point change under pressure?
yes
Is boiling point a chemical or physical?
Boiling Point is a physical change because the compound itself, while changing from a solid to gas, does not change otherwise.
The boiling point of a liquid can change with air?
The boiling point of a liquid can change with air pressure. As air pressure decreases, the boiling point of a liquid also decreases, meaning it will boil at a lower temperature. Conversely, as air pressure increases, the boiling point of the liquid increases, requiring a higher temperature to boil.
Is water boils an element compound or a mixture?
Water boiling is a phase change, which is a kind of physical change.
