boiling temperature remains same. air temperature varies . in mountains air temperature is lower. as surrounding temperature is lower water boils faster.,.or in other words heat transfer occurs faster due to difffernce in temperature. sorry to disagree the higher you go the lower the boiling point due to atmospheric pressure ex.. on Everest they cannot boil water hot enough to make tea
My approach aside from above statements is:
since boiling occurs when the pressure applied by the high kinetic energy molecules of water becomes same as that of atmospheric pressure. And since the pressure at mountains is low therefore boling temperature is lower in the same way.
A good example is of pressure cooker,
due to steam tightness, high pressure is generated in pressure cookers which thus increases the temperature of water inside because the boiling point of water is increased. Thus cooking food at high temperatures in few minutes.
hope that the question is anwered. regards!:-)
The boiling point of water can vary based on elevation. More specifically it varies based on relative pressure. Air is a fluid just like water. Everyone knows that the deeper you go in the water, the higher the pressure, and the shallower you go, the less the pressure. Going higher up on a mountain is like going shallower in the water. The air pressure drops as you go up and so does the boiling point of water.
This same concept is used by water distilling plants. A vacuum is drawn (a pressure less than atmospheric pressure of 14.7psia) on the region where the water is boiled and lowers the boiling point. Most will achieve a vacuum that allows the water to boil at 165F.
The boiling point of water at sea level (14.7psia) is 212F. A change in elevation changes the atmospheric pressure which changes the boiling point. A drop in pressure lowers the boiling point and an increase in pressure raises the boiling point.
Water boils at a lower temperature in a higher-altitude kitchen. Think of air pressure as 'keeping the lid on' steam. You can then see why it's easier to boil water when there is less air pressure ... which is exactly the situation up on a mountain. Air pressure is just the weight of the air that's up OVER you. As you rise to a higher altitude, more of the atmosphere is under you, and less is above you, so the air pressure is reduced.
Lower because of the lower pressure.how would the boiling point be affected in a pressurized boiler system.explain
This will depend on the altitude of the mountain, but as a rule, the higher the altitude, the lower the boiling point.
The easiest way to increase the boiling point of water is to boil it inside a pressure cooker. Adding salt will also increase the boiling point, but only slightly.
it willl fall down
the temperature stays the same
air pressure
dont no
cold water does.
Fresh water under atmospheric pressure boils at 100 C or at 212 F
at normal atmospheric temperature (in plains) it boils at 100oC
The liquid with low boiling point.
Water boils at 100 degrees Celsius and freezes at 0 degrees Celsius.
cold water does.
Water boils at 100 Celsius at a mercury barometer reading of 760mm. At higher pressures, the boiling point is higher. Conversely, at lower pressures - high up mountains, water boils at much lower temperatures.
Pressure cookers work because when you increase pressure, water boils at a higher temperature. Water normally boils at 212 degrees F. Under 15psi of pressure (standard in a pressure cooker), it boils at 257 degrees F. Since your food is cooking at a higher temperature, it will cook faster.
water boils at 100c, but as the temp above zero rises, more and more water turns to vapour, hence clothing dries quicker the higher the temperature.
when water boils it evaporates in to air
saltwater boils the fastest
when water boils it simply evapourates and broke steamy particles
Water boils at 100 degrees Celsius
"The sky is blue." "She is reading a book." "Water boils at 100 degrees Celsius." "The cat is sleeping on the couch." "Mountains are majestic."
The water that boils fasteris fresh water because salthas an effect on water.
Steam condences into water, water freezes in to ice, ice melts into water, water boils to steam
water because when they make maple syrup it is 95% water and to make the syrup better they boil off the water
