A mixture of $0.220$ moles $\ce{CO}$, $0.350$ moles $\ce{H2}$, and $0.640$ moles $He$ has a total pressure of $\ce{2.95 atm}$. What is the pressure of $\ce{CO}$?

Consider the radiation pressure on an object in outer space. Explain why, all else being similar, this pressure has a larger effect on the motion of a small particle than on a large particle.

Water at $15^\circ C$ and 1 atm pressure is heated to $100^\circ C$ at constant pressure. Using coefficient of volume expansion data, determine the change in the density of water.

Repeat the questions in earlier problem when we assume that friction causes pressure drops in the burner and on both sides of the regenerator. In each case, the pressure drop is estimated to be $2 \%$ of the inlet pressure to that component of the system, so $P_3=588\ \mathrm{kPa}, P_4=0.98\ P_3$, and $P_6=102\ \mathrm{kPa}$.

Solve for the new pressure, in atm, for each of the following, if n and V are constant:

a. A gas with an initial pressure of 1.20 atm at $75{ }^{\circ} \mathrm{C}$ is cooled to $-32{ }^{\circ} \mathrm{C}$.

b. A sample of $\mathrm{N}_2$ with an initial pressure of 780 mmHg at $-75^{\circ} \mathrm{C}$ is heated to $28^{\circ} \mathrm{C}$.

A multifluid container is connected to a U-tube. For the given specific gravities and fluid column heights, determine the gage pressure at $A$. Also, find the height of a mercury column that would create the same pressure at $A$.

Find your weight in newtons. Then, calculate the pressure in pascals that would be created on the oil in a $20$-mm-diameter cylinder if you stood on a piston in the cylinder. Convert the resulting pressure to psi.

Find the expression for the ratio of the stagnation pressure after a shock wave to the static pressure before the shock wave as a function of k and the Mach number upstream of the shock wave $M_{a1}.$

A large truck tire is inflated to a gauge pressure of 80 psi. The total area of one sidewall of the tire is 1,200 in. $^2$. What is the outward force on the sidewall because of the air pressure?

What is the minimum partial pressure of $\mathrm{H}_2$ required for the preceding reaction to be spontaneous in the forward direction at $25^{\circ} \mathrm{C}$ if the partial pressure of $\mathrm{HI}$ is $0.94$ ?

One mole of oxygen gas is at a pressure of 6.00 atm and a temperature of $27.0 ^ { \circ } \mathrm { C }$. If the gas is heated so that both the pressure and volume are doubled, what is the final temperature?

Air flows at Mach number of $1.5$, static pressure $95 \mathrm{kPa}$, and is expanded by angles $\theta_1=15^{\circ}$ and $\theta_2=15^{\circ}$, as shown. Find the pressure changes.

Calculate the water pressure (in $\mathrm{kPa}$ ) that must be on the ground to supply a water pressure of $252 \mathrm{~N} / \mathrm{cm}^2$ on the third floor, which is $9.00 \mathrm{~m}$ above the ground?

One mole of oxygen gas is at a pressure of 6.00 atm and a temperature of $27.0 ^ { \circ } \mathrm { C }$. If the gas is heated at constant volume until the pressure triples, what is the final temperature?
