Under what condition is pressure altitude and density altitude the same value?
Pressure altitude and density altitude are the same value when the atmospheric conditions are standard (i.e., International Standard Atmosphere conditions). This typically occurs at sea level with a standard barometric pressure of 29.92 inHg and a standard temperature of 15 degrees Celsius.
What is air pressure at an altitude of 34 feet?

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.
Why does the height of the cloud base change every day?
The height of the cloud base can change daily due to factors such as variations in temperature, humidity, and air pressure. These changes can influence the altitude at which clouds form and the height at which their bases are found in the atmosphere. Atmospheric conditions are dynamic and can vary from day to day, leading to fluctuations in cloud base height.
Why does atmospheric pressure change as you go up in altitude?
Atmospheric pressure decreases with altitude because there are fewer air molecules above, causing less weight of air pushing down from above. This leads to lower pressure as you go higher in altitude.
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.
Is air pressure the same at high altitudes?
No, it is not. The pressure decreases as the altitude increases.
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 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.
How does temperature change as height increases the troposphere?

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.
How does the altitude of Polaris change with latitude?
the altitude of polaris is same as the latitude of your location assuming that you are in the northern hemisphere
Is density of air same everywhere?
No, the density of air can vary depending on factors such as altitude, temperature, and pressure. At higher altitudes, the air density is lower due to lower pressure. Conversely, at sea level, air density is higher due to greater pressure.
