A liquid boils when the molecules are going fast enough to create vapor pressure equal to the atmospheric pressure. The higher the temperature, the faster the molecules are moving. Temperature measures the average kinetic energy of the molecules. So when you heat water to make it boil, you are actually providing enough heat energy to be converted into kinetic energy, so the molecules are moving fast enough, to produce enough vapor pressure to push the air out of the way, so the water molecules can get out of the water and into the air. (What a run on sentence)
So when you go up on top of a mountain where the air pressure is less, so it is easier for the water molecules go fast enough to produce enough water vapor pressure to push the air molecules out of the way.
So the Boiling point for a liquid on top of a mountain is lower than for the same liquid at sea level.
I wonder if any teachers besides me tell students that the air molecules above a pan of water are colliding with the water molecules in the pan, so the water molecules can not produce ……
As elevation increases boiling point decreases. The reduction in boiling point is because of reduced air pressure. Theoretically, water will boil a 0 degrees C in a pure vacuum.
The boiling temperature of water at sea level is higher than the boiling temperature at the peak of a mountain.
atmospheric pressure is lower and the boiling point is less
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
yes it is. The boiling point of a liquid is affected by the atmospheric pressure, so it is higher at sea level than it is at high altitude. Also depends on the purity of liquid
At sea level, 1 atm, the melting point of water is 0 oC and the boiling point of water is 100 oC.
The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.
Yes because it when it hit the mountain it is not right compared to a solid construction pint
atmospheric pressure is lower and the boiling point is less
The boiling point of a liquid is defined as when the vapour pressure of that liquid is equal to the atmospheric pressure. On mountains, the air pressure is lower than at sea level, so it follows that the boiling point of water is lower there.
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
yes it is. The boiling point of a liquid is affected by the atmospheric pressure, so it is higher at sea level than it is at high altitude. Also depends on the purity of liquid
because of the air pressure diference .
Boiling point is the temperature at which the vapour pressure of liquid equals the pressure surrounding the liquid and the liquid changes into vapour whereas, normal boiling point can be defined as the case in which, vapour pressure of liquid equals defined atmospheric pressure at sea level, 1 atmosphere.
At sea level, 1 atm, the melting point of water is 0 oC and the boiling point of water is 100 oC.
I think that the temperature required to boil water is lower at high altitudes (where the atmospheric pressure is lower) than at sea level.
Water boils faster on top of a mountain than at sea level because the boiling point of water is reduced with reduced atmospheric pressure.
At sea level, liquid water boils and becomes a gas at 212º F, or 100º C. Due to lower surrounding pressure it has a lower boiling point at higher altitudes (ex. boiling point is 202º F in Denver, CO, about 5,000ft. above sea level), and a higher boiling point at lower altitudes.
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.
