The boiling point of air is not a fixed value because air is a mixture of gases. However, the boiling pressure of pure nitrogen, which makes up the majority of air, is about 760 mmHg at 70 degrees Fahrenheit.
As you go higher the pressure decreases and the boiling point decreases too, this is because on surface of the earth the molecules are close together than as you go higher e.g if water boils at 100 deg C at sea level, on mount Everest water would boil at around 70 deg C. so pressure is very important factor in all our daily lives
At a vapor pressure of 70 kPa, the temperature of water would be approximately 63.5 degrees Celsius. This temperature corresponds to the boiling point of water at that specific pressure.
At 10,000 feet, the atmospheric pressure is approximately 70% of the pressure at sea level. This is because air pressure decreases with increasing altitude due to the weight of the air above pressing down.
As a liquid is under more and more pressure it's boiling point gets higher and higher. This is because it take more energy to move the molocules in a closed space. The opposite effect can be seen when water is placed in a vaccuum. If strong enough, the water can boil at room temperature because it's boiling point gets so low. The boiling point will increase. The reverse is also true. The boiling point of water on top of Mt. Everest is around 70 degrees celcius because the pressure is so low.
Water will boil at approximately 120.6 degrees Celsius when the external pressure is 31 kPa. This is lower than the standard boiling point of water at 100 degrees Celsius due to the reduced pressure.
As you go higher the pressure decreases and the boiling point decreases too, this is because on surface of the earth the molecules are close together than as you go higher e.g if water boils at 100 deg C at sea level, on mount Everest water would boil at around 70 deg C. so pressure is very important factor in all our daily lives
The boiling point on Mount Everest - whether at its base or on its summit - is the boiling point of water at different pressures. Within the relevant range of atmospheric pressure, the boining point ranges from around 100 deg C to 70 deg C.Water does not boil at room temperature and so the comparison is somewhat nonsensical.
sin 70 deg. = 0.9397
60 deg F = 15.5... deg C 70 deg F = 21.1... deg C
sin(70 deg) = 0.9397 approx.
68, because it appears more than any other number.
The sum of all three angles is 180 deg so the answer is 180 - (30 + 70) = 80 deg.The sum of all three angles is 180 deg so the answer is 180 - (30 + 70) = 80 deg.The sum of all three angles is 180 deg so the answer is 180 - (30 + 70) = 80 deg.The sum of all three angles is 180 deg so the answer is 180 - (30 + 70) = 80 deg.
If you were to travel to Denver, the mile high city, air pressure is reduced. This makes it easier for gas molecules to escape the liquid, hence the boiling point lowers. On the other hand, when pressure increases, gases have a harder time escaping the liquid so the boiling point must increase.
