Correct, but he wants us to find the pressure outside of the plane at 10,000 meters as well as the temperature of the air as it is being pressurized but before the plane's air conditioner cools it off.

This was a question the teacher gave us to think about over the weekend. The only clue he gave us in class is: 101325 Pa = (1.29 kg/m3)(h) where h = 8015 meters. He told us to use air density 1.29 kg/m3 but that does not make sense because dry air at sea level is 1.29 kg/m3 but as...

The air temperature at an altitude of 10,000 meters is a chilling -35º C. Cabin temperatures in airplanes flying at this altitude are comfortable because of air conditioners rather than heaters. A.) Find the pressure at 10,000 m and B) Find the temperature of the air before the air...

I would like to thank everyone that tried to help me. It turns out that I was using the right formula all along. Why my prof. tried to have me do it the hard way is one answer that I will never know. When I asked him he didn't even know. But thanks again for your help.

For the volume of 2000 cm"3" (2.000 L) and height of 18.0 cm I have a radius of 5.9471. For the height change I used the linear expansion formula and got "delta" h = 0.028512. Now to find the "delta" radius I tried to two different ways: Using the change in volume from (9.0E-4)(2000)(66)...

Sort of, I have to take into account expansion for the turpentine AND the aluminum cylinder. My physics prof. told me to use this formula: New Volume = pi(r + “delta” r)"squared" (h + “delta” h) I could then solve the problem. However, when I do this equation I come up with a huge number...

I need help with coming up with a formula for this question: A hollow aluminum cylinder 18.0 cm deep has an internal capacity of 2.000 L at 18 C. It is completely filled with turpentine and then warmed to 84 C. How much turpentine overflows? If the cylinder is then cooled back to 18 C, how...
