9. ssm When a .22-caliber rifle is fired, the expanding gas from the burn-ing gunpowder creates a pressure behind the bullet. This pressure causesthe force that pushes the bullet through the barrel. The barrel has alength of 0.61 m and an opening whose radius is 2.8 × 10-³ m. A bullet(mass = 2.6 X 10-³ kg) has a speed of 370 m/s after passing through thisbarrel. Ignore friction and determine the average pressure of the expand-ing gas.

Given data The length of the barrel is s=0.61 m The radius is r=2.8×10-3 m The mass of the bullet is…

A high-pressure gas cylinder contains 50.0 L of toxic gas at a pressure of 1.55 × 107 Pa and a temperature of 25.0°C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature (-78.5°C) to reduce the leak rate and pressure so that it can be safely repaired. What is the final pressure, in pascals, in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? To what temperature, in kelvins, must the tank be cooled from its initial state to reduce the pressure to 1.00 atm (assuming the gas does not change phase and that there is no leakage during cooling)?
2.5 mol of monatomic gas A initially has 5000 J of thermal energy. it interacts with 3 mol of monatomic gas B, which initially has 8000 J of thermal energy. How much energy will be exchanged between the two gases while the system is coming to thermal equilibrium?

90. A single gas molecule of inertia m is trapped in a box and travels back and forth with constant speed v between opposite walls A and B a distance € apart. At each collision with a wall, the molecule reverses direction without changing speed. Write algebraic expressions for (a) the magnitude of the change in momentum of the molecule as it collides with wall B, (b) the amount of time that elapses between collisions with wall B; (c) the number of collisions per second the molecule makes with wall B, and (d) the change in momentum under- gone by wall B, per second, as a result of these collisions. 00.
During inhalation, a person's diaphragm and intercostal muscles contract, expanding the chest cavity and lowering the internal air pressure below ambient so that air flows in through the mouth and nose to the lungs. Suppose a person's lungs hold 1260 mL of air at a pressure of 1.00 atm. If they expand their chest cavity by 485 mL while keeping their nose and mouth closed so that no air is inhaled, what will be the air pressure in their lungs in atm? Assume the air temperature remains constant. HINT atm
In period of 1.0 s, 5.0×1023 nitrogen molecules strike a wall of area 8.0 cm2. If the molecules move at 300.0 m/s and strike the wall head-on in perfectly elastic collision, find the pressure exerted on the wall.

A gas fills the right portion of a horizontal cylinder whose radius is 5.80 cm. The initial pressure of the gas is 2.64 x 105 Pa. A frictionless movable piston separates the gas from the left portion of the cylinder that is evacuated and contains an ideal spring, as the drawing shows. The piston is initially held in place by a pin. The spring is initially unstrained, and the length of the gas-filled portion is 27.1 cm. When the pin is removed and the gas is allowed to expand, the length of the gas-filled chamber doubles. The initial and final temperatures are equal. Determine the spring constant of the spring.

158 J of energy is transferred to a system consisting of 2.0 moles of an ideal gas. If the volume of this gas stays at a constant 2.8 L, calculate the change in internal energy of the gas.

Oxygen with mass of m1=6 g and temperature T1=300 K is in a container under pressure p1= 9.66·105 Pa. If an unknown gas with mass m2= 3 g and temperature T2=330 K is placed in the same container, then the gas is under pressure p2=9·105 Pa. Find the molar mass of the unknown gas.
A moonshiner makes the error of filling a glass jar to the brim and capping it tightly. The moonshine expands more than the glass when it warms up, in such a way that the volume increases by 0.5% (that is, ΔV/V0 = 5 10-3) relative to the space available.
A sample of gas is compressed to one-third of its initial volume at a constant pressure of 1.25 × 105 Pa. During the compression 100J of work is done on the gas. What is the final volume of the gas?
