All gases become liquids when cooled to their what point?
All gases become liquids when cooled to their respective boiling points. At this temperature, the vapor pressure of the gas matches the external pressure, causing the gas to condense into a liquid state.
What is the saturation temperature of vapour or the boiling temperature of a liquid?
The saturation temperature of a vapor is the temperature at which it condenses to a liquid at a given pressure. It is also known as the boiling temperature of a liquid, as it is the temperature at which the vapor pressure of the liquid equals the surrounding pressure, resulting in boiling.
Are there other liquids besides water that boil at 100 degrees celsius?
Yes, there are other liquids that can boil at 100 degrees Celsius under specific conditions, such as certain mixtures or solutions. For example, a saline solution or sugar solution can have a boiling point around this temperature depending on concentration and atmospheric pressure. Additionally, some liquids may have boiling points that approach 100 degrees Celsius at higher altitudes where atmospheric pressure is lower. However, pure water at standard atmospheric pressure is the most commonly recognized liquid with this boiling point.
What effects pressure?
Pressure can affect the physical properties of gases, liquids, and solids. For gases, pressure influences volume and temperature through the ideal gas law. In liquids, pressure can impact density and boiling point. In solids, pressure can cause compression or expansion, altering the arrangement of atoms and thus changing the material's properties.
How is boiling point used in chemistry?
If you know a boiling point, you can separate two different liquids that are mixed together. If the two liquids have different boiling points, you can boil them both. One of the liquids will reach its boiling point before the other liquid and start to evaporate. One of the liquids will have evaporated and will be separated from the liquid with the higher boiling point. This is called distillation. Jarachia ~ x
When is boiling point?
Boiling point is when the liquids pressure equals the pressure of the atmosphere.
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.
How is evaporation different from boiling?
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c
All gases become liquids when cooled to their what point?
All gases become liquids when cooled to their respective boiling points. At this temperature, the vapor pressure of the gas matches the external pressure, causing the gas to condense into a liquid state.
What are the factors that affect the boiling of liquids?
Short answer: Pressure. Long answer: Pressure changes the boiling point of a substance. The higher the pressure, the higher the boiling point, and vice versa. For example, boiling water in the mountains is easier than boiling water at sea level. Note that boiling water is not necessarily hot. You can boil water at room temperature if the pressure is low enough (For example, using a vacuum generator)
Is it true that the boiling point of a liquid remains constant at all altitudes?
No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.
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 is the saturation temperature of vapour or the boiling temperature of a liquid?
The saturation temperature of a vapor is the temperature at which it condenses to a liquid at a given pressure. It is also known as the boiling temperature of a liquid, as it is the temperature at which the vapor pressure of the liquid equals the surrounding pressure, resulting in boiling.
Describe the difference if any there would be between the boiling point of alcohol measured in Houston and in Denver the mile high city?
The boiling point of alcohol in Houston would be lower than in Denver because Houston is at a lower elevation than Denver. At higher elevations like Denver, the air pressure is lower, which leads to lower boiling points for liquids. So, alcohol would boil at a higher temperature in Denver compared to Houston.
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.
How does the boiling point in mountains change?
The boiling point of water (or other liquids) depends on the pressure acting on it. As you increase the altitude, the atmospheric pressure decreases and as it does, the boiling point of the liquid decreases. The atmospheric pressure at the summit of Mount Everest is approx one thrid the pressure at sea level and so water boils at approx 71 deg C.
Do liquids have a fixed temperature but no fixed shape?
Yes, liquids have a fixed temperature at a specific pressure until they reach their boiling point, at which point they turn into gas. Liquids do not have a fixed shape and take the shape of their container.
