Under what condition is pressure altitude and density altitude the same value?
at standard temperature
How does altitude affect the quantitiy of oxygen molecules?
Their proportion remains almost the same with altitude however the absolute number falls off as the pressure decreases with altitude.
Is the weather the same day after day?
no, it always change because of humidity, pressure, wind, cloudiness, temperature, and pressure. these 6 elements completes the weather!
As altitude increases from the tropopause to the mesopause the atmospheric temperature will?
the temp stays the same
Is it a fact that as altitude increases pressure decreases?
That is correct. If you think of the air as being a column of molecules, you can visualize that the mass of molecules in that column is forced downward by gravity. A 1cm square column extending upward to the top of the atmosphere weighs approximately 2.2 pounds. At an altitude further up the column where fewer molecules comprise a lesser mass they would exert proportionately less force. Another way to measure the weight of this column of air is by the pressure it exerts at a given point. Temperature also has an effect on the pressure of air due to a change in the density of the air mass, thus two columns of air at at the same altitude might have different pressures because their temperatures are different. Generally, cold air has a higher pressure than warm air at the same altitude. The decrease in pressure as altitude increases is called the pressure lapse rate, and has been tabulated for a "standard atmosphere" (one where the pressure and temperature at sea level are 29.92 in Hg (inches of mercury) and 15 deg C respectively). Obviously, this varies in real world conditions but is approximately 1 in Hg per 1000 ft. The term lapse rate also applies to temperature changes with altitude and is approximately 2 deg C per 1000 ft on average depending upon the the moisture content of the air.
What condition is pressure altitude and density altitude the same value?
At standard temperature.
Under what condition is pressure altitude and density altitude the same value?
at standard temperature
What happens to pressure as altitude increased?
As altitude increases (i.e. when you get higher) pressure falls off inversely; a change near the higher reaches will not have as much of a pressure differential as the same distance change lower down.
Does water boil the same at sea level as it does at higher elevations?
Due to lower atmospheric pressure at altitude, water will boil at lower temperature.
Is air pressure the same at high altitudes?
No, it is not. The pressure decreases as the altitude increases.
How does temperature change as increases in the troposphere?
As the altitude increases in the Troposphere, The air temperature decreases. When about 1 kilometer increases in altitude, the air cools about 6.5 degrees Celsius. And at the very top of the Troposphere the air temperature stays the same at around -60 degrees Celsius.
Is the temperature for poultry the same at high altitude?
yes the internal temperature for doneness is the same. But the length of time you roast it in the oven will vary from sea level to high altitude.
How does temperature change as height increases the troposphere?
As the altitude increases in the Troposphere, The air temperature decreases. When about 1 kilometer increases in altitude, the air cools about 6.5 degrees Celsius. And at the very top of the Troposphere the air temperature stays the same at around -60 degrees Celsius.

Which temperature change would cause the volume of a sample of an ideal gas to double when the pressure of the?
For the pressure to remain the same, the temperature would double if the volume also doubled.
Is the altitude higher or lower if the temperature remains the same?
lower
Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
