Water pressure at the bottom of the ocean arises from the weight of the overlying water. Does this mean that the water exerts pressure only in the downward direction? Explain.

A gas has an initial volume of $39$ ml at an unknown pressure. If the same sample occupies $514$ml at $720$ torr, what was the initial pressure?

A certain gas has a volume of $420 \mathrm{cm}^{3}$ at a pressure of 720 mm. What will its volume be if the pressure is increased to 840 mm?

The deflection on the manometer is $h$ meters when the pressure in the tank is $150\ \mathrm{kPa}$ absolute. If the absolute pressure in the tank is doubled, what will the deflection on the manometer be?

Prove for an ideal gas that (a) the P = constant lines on a T-v diagram are straight lines and (b) the high-pressure lines are steeper than the low-pressure lines.

How does the solubility of a gas in a liquid depend on pressure? How does this pressure dependence account for the bubbling that occurs upon opening a can of soda?

Define the term partial pressure.

Consider the scalar field (pressure field) given by $f(x, y)=9 x^2+4 y^2$. Find the region in which the pressure varies between $36$ and $144$ .

Boiling and freezing occur when water is subjected to (a) decreased temperatures. (b) decreased atmospheric pressure. (c) increased temperatures. (d) increased atmospheric pressure.

The deepest ocean trench is about $10.9 \mathrm{~km}$ deep. Find the pressure at this depth. (b) How many times larger than atmospheric pressure is this?

What is the pressure inside the tube?

Atmospheric pressure Under certain conditions, the atmospheric pressure $p$ at altitude $h$ is given by the formula $p=29 e^{-0.000034 h}$. Express $h$ as a function of $p$.

The gage pressure in a liquid at a depth of $2.5 \mathrm{~m}$ is read to be $28\ \mathrm{kPa}$. Find the gage pressure in the same liquid at a depth of $9 \mathrm{~m}$.

A gas syringe contains 50. mL of CO2 at 1.0 atm pressure. What is the pressure inside the syringe when the plunger is depressed to 25 mL?
