pressure/temperature is 29.92 in. (1,013.25 mb) and 59°F (15°C).

How do you find the temperature at sea level?

As we can see, a 35000 ft altitude is within the troposphere where temperature decreases with altitude. We subtract the altitude at our current location from 35000 ft and multiply the result by 0.00356 . 35000 – 2640 = 32360 . The result of the product will be the temperature difference: 32360 * 0.00356 = 115.2 °F .

Is the temperature constant at sea level?

What is the temperature at 5000 feet?

Since it’s about 5,000 feet between the summit and the base of the mountain, the temperature at the base village should be about 27°F warmer than at the top (5,000 feet elevation change at 5.4°F per 1,000 feet equals about 27°F temperature increase). So the temperature at the base should be around 32°F.

How cold is it in space?

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).

Is it hotter at higher elevations?

The basic answer is that the farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.

How cold is it at 40000 feet?

Between 9,000 and 12,000 metres (30,000 and 40,000 feet), the cruising altitude of most jet aircraft, air temperatures range from −40 to −70 °F (−40 to −57 °C). Modern aircraft have sealed cabins and heaters to protect pilots and passengers from wind blasts and cold air.

What does the mesosphere do for us protect us from )?

The mesosphere protects the Earth from meteors and asteroids by burning them up before they can reach its surface.

What is the air temperature?

Air temperature is a measure of how hot or cold the air is. It is the most commonly measured weather parameter. More specifically, temperature describes the kinetic energy, or energy of motion, of the gases that make up air.

What is RH humidity?

The basics. Put simply, relative humidity (RH) is a measure of the water vapor content of air. More explicitly, it is the amount of water vapor present in air expressed as a percentage (%RH) of the amount needed to achieve saturation at the same temperature.

How high do planes fly in feet?

Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman.

What height do planes fly at?

According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level.

How warm is the Earth 200 feet down?

Soil can hold heat better than air does.

From about 30 to 200 feet below the surface, the soil temperature is relatively constant (about 55 degrees F.).

Do people live in Oymyakon?

What is the hottest city on Earth?

Mecca, in Saudi Arabia, is the warmest inhabited place on earth. Its average annual temperature is 87.3 degrees Fahrenheit. In summer, temperatures can reach 122 degrees Fahrenheit. The city is located in Sirat Mountains, inland from the Red Sea, 900 feet above sea level.

What is the warmest place on Earth?

Death Valley, California

According to the World Meteorological Organization’s Global Weather &amp, Climate Extremes Archive, temperatures in Death Valley reached international extremes when they hit 134 degrees Fahrenheit in 1913 — the hottest temperature recorded anywhere in the world.

What temperature do planes fly at?

“Aircraft at cruising altitude will often experience temperatures of minus 50 to minus 70 F for hours on end.” Generally, engines like cold weather. Since cold air is denser than warm air, engines provide more power because there are more oxygen molecules.

How cold do planes fly?

Yes, at a flying altitude planes experience temperatures of -40C to -57C. Therefore freezing weather on the ground usually doesn’t affect airplanes.

Can you breathe 30000 feet?

Somewhere between 30,000 and 40,000 feet the pressure around you becomes far too low to push those oxygen molecules across the membranes in your lungs, and you get hypoxic (altitude sickness). If you try to breathe 100 percent oxygen above 40,000 feet for very long without a special type of mask, you’ll die.

What happens if you bleed in space?

In space, blood can splatter even more than it usually does on Earth, unconstrained by gravity. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.

How cold is Moon?

When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C). There are also no seasons on the Moon. We have seasons because the Earth tilts on an axis at roughly 23.5 degrees.

Why is space dark?

Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.

Is it hotter on a mountain?

When the air is high on the mountain, it spreads out. This is like your big square. The same amount of heat is now in a bigger space, so it is more spread out. So the air is colder on top of mountains because there is less air pressure.

Why are mountain tops cold?

As air rises, the pressure decreases. It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level.

Why does it feel warmer in the mountains?

On a sunny day you will get more solar radiation at high altitude, especially around mid day, and that will be in addition to the shade temperature which weather forecasters use. When walking from A to B in the mountains, we usually exert ourselves more than we would at sea level, and therefore we feel hotter.

Can a plane fly over Mount Everest?

The first men to fly over Mount Everest did so in an unpressurized biplane. The two planes fly towards Lhotse and Everest at 32,000 feet. Though the 29,029-foot-high summit of Mount Everest was first conquered on foot by Tenzing Norgay and Edmund Hillary in 1953, it was conquered by air two decades earlier.

Why do planes not freeze in the air?

If it drops below the dew point, dew forms, if it drops below that and freezing, frost forms. In flight, the high speed air flow over the aircraft keeps its skin at essentially the same temperature as the air so it doesn’t drop in temperature the same way.

At what temperature does jet fuel freeze?

After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit. Jet fuel freezes at around -40 degrees Fahrenheit, but it will work just fine as long as it’s kept above that temperature on the ground.

What is the best air pressure for humans?

Vanos said people are most comfortable with barometric pressure of 30 inches of mercury (inHg). When it rises to 30.3 inHg or higher, or drops to 29.7 or lower, the risk of heart attack increases.

Which location has the highest air pressure?

The highest barometric pressure ever recorded was 1083.8mb (32 in) at Agata, Siberia, Russia (alt. 262m or 862ft) on 31 December 1968. This pressure corresponds to being at an altitude of nearly 600 m (2,000 ft) below sea level!

What is the pressure exerted by air called?
