The boiling point would be 35 degrees Celsius. Use a graph comparing vapor pressure to temperature, go to the point where propanone is at 48 kpa, and see what the temperature is.

The temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point
What are the 2 kinds of vaporization?
The vaporization that takes place below the surface of liquid is called boiling. The other one that takes place at the surface of a liquid is called evaporation
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.
When vaporization takes place on the surface of a liquid is called?
If vaporization takes place at the surface of a liquid, it is called evaporation. but when evaporation occurs throughout the substance it is called boiling.
What is the surface area of a pressure vessel?
The answer depends on the pressure vessel.
On Venus the surface atmospheric pressure is about 90 earth atmospheres what is the Venusian atmospheric pressure in Kilopascals?
About 9.3 Megapascals
Which of the inner planets have atmospheres made up of mostly cardon dixiode?
Venus and Mars both have atmospheres composed of about 95% carbon dioxide. Mars's atmosphere is very thin, with a pressure of 0.7 kilopascals, compared to the Earth's 1013 kilopascals. Venus's atmosphere has a pressure at the surface of about 94,000 kilopascals, about 0.6 tons per square inch.
What happens to the boiling point of a liquid if the pressure exerted on a surface is reduced?
The boiling point lowersas the pressure is lowered.
How does boiling point differ from normal boiling point?
The boiling point and normal boiling point are related concepts, but they have specific differences. Boiling Point: The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas or vapor. At the boiling point, bubbles of vapor form within the liquid and rise to the surface, resulting in a continuous phase change from liquid to gas. Different substances have different boiling points, which can be influenced by factors such as atmospheric pressure and the strength of intermolecular forces within the liquid. Normal Boiling Point: The normal boiling point of a substance is the temperature at which it boils when the atmospheric pressure is at the standard pressure of 1 atmosphere (atm), which is equivalent to 101.325 kilopascals (kPa) or 760 millimeters of mercury (mmHg). This standard pressure is typically found at sea level.
When atmospheric pressure increases what happpens to the boiling temperature of a liquid?
The boiling temperature of a liquid increases as the gas pressure a the liquid's surface increases.
What does an increase in pressure on the surface of water do to the boiling point?
It will raise the boiling point. This why, for example, car radiators have a pressure cap. This causes a rise in the boiling point of the water and it is less likely to boil.
The temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point
What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
Why is the boiling point not the same in Henderson as it is at sea level?
The Boiling Point of a Liquid (a Fluid) is dependent on its Surface Pressure (air pressure). The Air Pressure (due to increased altitude) is LOWER in Henderson than at Sea Level.
How a liquid can be changed to gaseous form below its boiling point without supplying it with heat energy?
By reducing the pressure above the surface of the liquid. Because boiling point depends on the pressure around the liquid
When molecules from below the surface of a liquid become a gaswhat is happening?
Boiling - the vapor pressure exceeds atmospheric PLUS the pressure of the depth of the liquid.
How does boiling from evaporation?
Evaporation is much slower than boiling, and it can happen at any temperature (above zero Kelvin) whereas boiling only happens at the boiling point. Evaporation happens when a liquid molecule has enough energy to escape from the surface of a liquid - this is why you can smell perfume and why puddles disappear in warm weather As these molecules build up above the surface of the liquid, there is a build up of pressure. This is called the saturated vapour pressure. When the overall temperature of the liquid is high enough, the saturated vapour pressure increases until it is equal to atmospheric pressure - this is called the boiling point.
