A light layer of vacuum grease is applied to the rim of the belljar. Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.
What else can I help you with?
Is the boiling point a negative number for neon?
Whether or not the boiling point of neon is negative depends on the temperature scale used to describe the boiling point. If the boiling point is given in Celsius or Fahrenheit, the boiling point is negative. However, in Kelvin, which cannot be negative, the boiling point is positive.
How does the boiling point of saltwater compare to the boiling point of freshwater?
The boiling point of saltwater is higher than that of freshwater. This is because adding salt increases the boiling point of water. The exact boiling point increase depends on the concentration of salt in the water.
What is the boiling point for calcuim?
What is the boiling point for calcium?
Which boils quicker liquid with high boiling point or liquid with low boiling point?
A liquid with a lower boiling point will boil quicker because it requires less energy to reach its boiling point compared to a liquid with a higher boiling point.
How could you change the boiling and freezing temperature of water?
If you want to limit yourself to water only, you could change the pressure. That would greatly change the boiling point and slightly change the freezing point. If you don't care about limiting yourself to pure water, you can dissolve a salt or other substance in the water to lower the freezing point and raising the boiling point.
What is one physical property that could not be used to distinguish chlorine from oxygen?
Boiling point could not be used to distinguish chlorine from oxygen, as they both have different boiling points. Chlorine's boiling point is -34.6°C, while oxygen's boiling point is -183°C.
How could you demonstrate that gas has mass?
A perfect example would be boiling ice and watch it turn to gas.
Boiling point used in a sentence?
This is an example sentence for the words, boiling point. Dad was upset all day but he reached his boiling point when he could not find the remote.
How is boiling different from boiling point?
Boiling is the phase where the boiling occurs. The point at which the boiling occurs is the boiling point.
How could a liquids boiling point be used to determine if it is a mixture or a pare substance?
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
What is the boiling point of ununoctium?
The boiling point of ununoctium is not precisely known as it is a synthetic element that is highly unstable and decays quickly. However, estimates suggest it could potentially have a boiling point around -97 degrees Celsius.
Why the boiling point of a pure liquid is usually reported along with the pressure at which the boiling point was measured?
The boiling point of a liquid depends on the pressure applied to it: higher pressure raises the boiling point and lower pressure decreases it. By reporting the boiling point along with the pressure, it allows for accurate comparison and reproducibility of experimental results, as different pressure conditions can affect the boiling point.
How could you turn a gas into a liquid?
cool it below the boiling point
Why is the boiling point of a pure liquid usually reported along with the pressure at which the boiling point was measured?
Because the pressure could affect the temperature at which the water boils
What is the boiling point of riboflavin?
there is no boiling point
Which metal has lowest boiling point?
Mercury Hg -38.8' Now you could consider Hydrogen to be a metal if you are willing to get creative with the definition of metal. In that case it would be −259.16 °C
Is the boiling point a negative number for neon?
Whether or not the boiling point of neon is negative depends on the temperature scale used to describe the boiling point. If the boiling point is given in Celsius or Fahrenheit, the boiling point is negative. However, in Kelvin, which cannot be negative, the boiling point is positive.
