The pressure at 19km is 0.1 atm. Pressure is reduced to 1/10 th at every 19 km altitude increase.
If the pressure is 0.01 atm at an altitude of 38 km and 0.001 atm at...
1. A balloon at an altitude of 30 km is filled with helium gas at a pressure of 10-2 atm and a temperature of 250 K. Estimate roughly the number of helium atoms hitting each square nanometer of the inner surface of the balloon per nanosecond.
At the 18 km cruising altitude of Concorde, a passenger aircraft that flew at twice the speed of sound, the temperature was -57∘C. What was the Concorde's cruising speed?
temperature gradient is 25k/km
(b) The Earth's pressure gradient in the lithosphere is VP300 atm/km (the temperature gradient can be taken from the previous question). At a depth of 50 km, will it be more likely that albite forms or that jadeite+quartz forms? Explain.

1. For the earth, an estimate of the variation of pressure with altitude above the surface of the earth is made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. A significant error in this estimate arises from the assumption that the temperature of the atmosphere, T, is isothermal instead of decreasing with altitude. This decrease with altitude y in...
Question 2 10 pts What is the atmospheric pressure at a cruising altitude of 10 km? Use the scale height of H-7.4 km and the pressure at the sea level is 1013 hPa. Answer in hPa to three significant digits.
Consider a Boeing 777 flying at a standard altitude of 11 km with a cruising velocity of 935 km/h. At a point on the wing, the velocity is 280 m/s. Calculate the temperature and pressure at this point.
A sample of carbon dioxide gas at a pressure of 1.16 atm and a temperature of 221 °C, occupies a volume of 568 ml. If the gas is heated at constant pressure until its volume is 816 ml., the temperature of the gas sample will be Submit Answer Retry Entire Group 6 more group attempts remaining A helium-filled weather balloon has a volume of 774 L at 16.9°C and 754 mmHg.

1) Gas is confined in a tank at a pressure of 9.8 atm and a temperature of 26.5°C. If two-thirds of the gas is withdrawn and the temperature is raised to 90.0°C, what is the pressure of the gas remaining in the tank? 2) A weather balloon is designed to expand to a maximum radius of 17 m at its working altitude, where the air pressure is 0.030 atm and the temperature is 200 K. If the balloon is filled...
A helium balloon has a volume of 6.9 L at 28.5 °C and 1.00 atm pressure. The balloon rises to an altitude where the air pressure is 0.76 atm and the temperature is -21.0 °C. What is its volume when it reaches equilibrium at this altitude? (Note: Neglect tension forces in the material of the balloon.)
At an altitude of about 10.8 km, the temperature of the Earth's atmosphere is roughly-68 Celsius and the pressure is around 34.7 kPa. How many kg of Carbon Dioxide gas should be put in a balloon to fill it to 3200 mᵒ at that altitude? 3452 kg 2728 kg 3056 kg 2860 kg 3244 kg
