How does the boiling point different from lowland and highland?
The boiling point of a substance is lower at higher altitudes due to lower atmospheric pressure, which reduces the pressure exerted on the liquid. In contrast, at low altitudes with higher atmospheric pressure, the boiling point is higher as more pressure is needed to overcome atmospheric pressure.
What is the term used to describe the constant temperature at which a pure liquid changes to vapour?
Boiling point
What happens to the boiling point of water at altitudes above sea level?
The temperature decreases the higher you go.
What happens to the boiling point of water at altitudes above sea level xy?
Answer:The boiling point of water at sea level is 100oC (212oF). Water boils when the pressure of the vapor is equal to the surrounding pressure. Since atmospheric pressure is reduced at higher altitudes it takes less energy (and therefore less heat) to boil water. So to put it simply the higher your altitude the lower the boiling point.
Why does boiling water temperature remain constant at 100 degree Celsius till all the water vaporized?
The boiling point of water is the temperature at which the vapor pressure of water is equal to the atmospheric pressure. As long as there is liquid water present, the temperature will remain at the boiling point (100 degrees Celsius at sea level), because the energy is being used to convert the liquid water into vapor rather than increasing the temperature.
Is that true that boiling point of a liquid remains constant at all altitudes?
The boiling point is lower at high altitude.
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.
For any pure substance the boiling point and melting point will always remain?
The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
Does adding more heat to a bowl of water raise the boiling point?
No, the boiling point of the pure water remain constant at 100 0C, of course at standard pressure.
Is it true that boiling point of a liquid remains constant in all altitudes?
No. The higher the altitude the more difficult, and fuel expensive, to boil water.
What can you notice about the temperature of sea water during boiling?
The boiling point of sea water is higher compared with pure water. Temperature remain constant during boiling.
What is a thermobarometer?
An instrument that measured altitudes via the boiling point of water
Can the freezing point be lower than its boiling point in a constant pressure?
At a constant pressure, the freezing point is always going to be lower than the boiling point.
What can change the boiling point of water?
The boiling point of water can be affected by changes in atmospheric pressure. At higher altitudes where the atmospheric pressure is lower, the boiling point of water is lower. Conversely, at lower altitudes with higher atmospheric pressure, the boiling point of water is higher.
How would boiling point of ethanol be affected by high altitude?
The boiling point of ethanol would be lower at high altitudes compared to sea level. This is because the atmospheric pressure is lower at high altitudes, which requires less heat to reach the boiling point of a liquid like ethanol.
Is there any difference in boiling point of purewater in different altitude?
Yes. The boiling point of water is lower at higher altitudes because there is less atmospheric pressure.
How does the boiling point different from lowland and highland?
The boiling point of a substance is lower at higher altitudes due to lower atmospheric pressure, which reduces the pressure exerted on the liquid. In contrast, at low altitudes with higher atmospheric pressure, the boiling point is higher as more pressure is needed to overcome atmospheric pressure.
