Chapter 16, Problem 19E
Earth’s atmosphere is in hydrostatic equilibrium. What this means is that the pressure at any point in the atmosphere must be high enough to support the weight of air above it. How would you expect the pressure on Mt. Everest to differ from the pressure in your classroom? Explain why.

Atmospheric pressure on Earth at its surface is 101 KPa (101 kilopascals or 101,000 N/m2). Which of these statements is true.
If we pump out the gas in a closed container leaving only 1 billionth of the original gas, there will only be about 1000 atoms left in the container.
The number of atoms or molecules in the container depends on what the gas is composed of.
If we pump out the gas in a closed container leaving only 1 millionth of the original gas there will still be more than 1013 (10,000 billion) atoms per cm3 in the container.
The number of atoms or molecules in the container does not depend on temperature.
Make a plot of pressure vs altitude for a hydrostatic, isothermal atmosphere on Earth, assuming a surface pressure of 1 atm.
A helium weather balloon is inflated so that the pressure inside is at Earth's atmospheric pressure (approximately 101 kPa). If the balloon is then released on a planet whose thick atmosphere results in a pressure inside the balloon twice that of Earth's atmospheric pressure, what will happen to the balloon's volume?
It stays the same.
It decreases slightly.
It increases slightly.
It halves.

- The density of the atmosphere varies drastically with height, but you can use an average density from sea floor to the space in order to calculate its height. If we approximate this average density to be = 1 Kg/m³, what would be height of the atmosphere? HINT: Since the atmosphere is a fluid (in gas form), you can use the hydrostatic pressure formula (P pgh), just solve for h and use P = 1 atm. BTW, this is how the edge of space is defined, if you make it pass the height of the atmosphere you have reached space :)arrow_forwardIn order for a balloon launch to be interesting, we will want to tie some sort of payload to the balloon.
