Do all the liquids at their boiling points have same vapour pressure?

At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.

When does boiling point occur?
For water it is 100 degrees celsius, however it is different for other liquids ------------------------- Generally, boiling point is the temperature at which the liquid's vapour pressure is equal to the external atmospheric pressure.
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
What is the meaning of boiling in science terms?
Actually boiling is a point where the vapour pressure of any liquid (example: water) becomes equal to the surrounding pressure.
Boiling point temperature?
The boiling point is defined as the temperature that the liquid spontaneously turns into a vapour throughout the liquid. This is dependent on atmospheric pressure as the higher the pressure the more energy is required to produce the gas /vapour bubbles in the liquid. We see this effect when water boils and the surface is disturbed by the bubbles rising to the surface - it is boiling. Water boils at a little over 60 oC (140 oF) at the top of Mount Everest but at 100 oC (212 oF) at sea level ie 1 ATM pressure. When water is boiled at a higher location than sea level it will boil at less than 100 oC depending on atmospheric conditions.
What is a fountain of boiling water and steam?
it is the condensed water vapour and gas.

How can reduce the boiling point of methanol?
If we pressurize the liquid ( same like pressure coocker) its vapour pressure increases. As the vapour pressure increases boiling point increases and visa versa. Also to reduce the boiling temperature we can add another liquid with a lower boilng point in it so that its boiling point reduces. Exact boiling point can be determined with the known boiling poin t and ratios of the different liquids.
Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
How Does Pressure Affect The boiling points?
The boiling point of an element or a substance is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid.Vapour pressure or equilibrium vapour pressure is the pressure of a vapour in thermodynamic equilibrium with its condensed phases in a closed container.The vapor pressure of any substance increases non-linearly with temperature.Suppose we are at the boiling point....As pressure of surroundings increases we need to increase the vapour pressure so as to make the vapour pressure equal to the surrounding pressure...Now, to increase the vapour pressure we will have to increase the temperature....So When presure increase boiling point increases...when it decrease boiling point decreases...
What is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling
What is the boiling point of water vapor?
Water vapour doesn't boil, but liquid water's boiling point is 100 degrees C, or 212 degrees F.boiling point is that point at which the vapour pressure of a liquid become equal to the atmospheric pressure at a particular temperature.for exampleboiling point of water is 100 degree Celsiusthat isat this temperature vapour pressure of water is equal to the atmospheric pressureso there is no boiling point of water vapour since it is not a liquid and boiling point is only determined for liquids not gases or vapours .also vapour has 540 kilo calories of heat known as latent heat of vapourisation at 100 degree celsius.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
What is the effect of nature of liquid on the rate of evaporation?
heat, humidity,wind and the surface area of container that it is in.
What is the saturation temperature of vapour or the boiling temperature of a liquid?
Different liquids have different boiling temperatures, even the same liquid will have different boiling temperatures at varying pressures.
Why does pressured water have a raised boiling point?
Boiling is the phenomenon in which saturated vapour pressure becomes equal to the external pressure. Hence as we increase the external pressure then the boiling point has to increase so as to attain that pressure
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
Why an increase in vapour pressure stop boiling?
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.
