What is the temperature in the luggage area of an airplane during flight?
438587
It varies with planes and parts of the cargo hold.  There are places to ship animals and other things that can not be frozen, the other parts can reach the temp of the outside air which can be -50 or lower on long distance flights!

98.4degrees farenheit or 37 degrees celsius.it can vary a little.

For most airlines its between 162-182cm :)

In modern jets the air is taken from after several stages of compression at this point the air is relatively hot and can be allowed to cool through a small radiator before being depressurized.  The resulting depressurized air will be significantly cooler because it had lost energy when there was a heat differential between atmosphere and its pressurized state. This is why the air conditioning in an airplane needs assistance from a ground until the engines are operating.

32 degrees Fahrenheit.

Fresh air is from the engines.  The first stages of a jet engine compresses the air.  The air heats up when it's compressed.  Part of that compressed air is piped off and goes through heat exchangers, cooling it to about 32F.  That cool air and some of the hot air from the engine are combined to give a comfortable tempurature in the cabin.  This flow of air pressurizes the fuselage so that the passingers can breath normally.  Valves in the fuselage control this pressure, preventing over or under pressurization.

134 degrees F. if I remember correctly (Death Valley)

It's generally around 62- 68 degrees.\n\nThat's Fahrenheit,not Celsius !

Probably at least 65 degrees.  72 is room temperature.  I would complain if it was under 65 (too cold) or over 75 (wasteful)

Air is denser the lower you go on the earth, due to gravity pullin gthe air down. As you move up, there is more "room" for the air to expand. Air temp is just the measure of the net kinetic energy of the molecules of air. The faster and more there are, the hotter it is. therefore, as the air expands as it moves up into the atmosphere, it cools. On top of a mountain, there is less molecules actually hitting your skin, so it feels very cold.

At 60 degrees F and 29.92 inches of mercury the density of air is.0763 lb/cubic foot. At 0 degrees F it is .0862 lb/ cubic foot and at 100 degrees F it is .0708 lb/cubic foot.

Ice crystals form at high altitude.  Temperature drops approximately 5 degrees for every thousand feet.  If a plane is flying at 35 thousand feet, 35 X 5 = a temperature well below zero even on the warmest day at sea level...\n\nExhaust has water vapor in it that freezes and that is what we see.

I'm confused.  Some law enforcement aircraft have infared detection gear that senses gradient temperatures...the DEA for example uses this technology for interdicting drug shipments...is that what you're talking about or are you tallking about heat seeking weapons on police helicopters?

depends on the acceleration of the airplane or object. this found by vector addition. example: if an airplane or a rocket is falling freely (god forbid) all the objects inside will have 0 weight.
