Chapter 15, Problem 67GP
A student in a physics lab course has the task of measuring the pressure of a gas as a function of volume. Helium gas is placed in a cylinder that is fitted with a piston. By pushing the piston down, the student reduces the volume of the gas by a known amount and then measures the resulting gauge pressure (pressure relative to 1 atm). The measurements are made at room temperature (20°C). The resulting data are shown in the table.
| Volume (L) | Gauge Pressure (atm) |
| 0.2 | 112 |
| 0.4 | 5.03 |
| 0.6 | 3.06 |
| 0.8 | 2.03 |
| 1.0 | 1.42 |
Make a linearized plot of the pressure-versus-volume data. Determine the number of moles of helium in the cylinder by using a “best fit” to the data.

With the temperature held constant, the pressure of a gas in a cylinder with a movable piston is increased from 10 kPa to 90 kPa. The initial volume of the gas in the cylinder is 0.36 m squared. What is the final volume of the gas after the pressure is increased?
Use the right formula to solve and get the correct answer.
A cylinder is filled with 10.0L of gas and a piston is put into it. The initial pressure of the gas is measured to be 275.kPa .The piston is now pulled up, expanding the gas, until the gas has a final volume of 82.0L. Calculate the final pressure of the gas. Round your answer to 3 significant digits.
A hollow spherical container has an outer diameter of 10.50 cm. The thickness of the walls is 0.50 cm. The container is filled with water. Water molecules are approximated to be spheres with a diameter of 275 pm. How many water molecules are present inside of the container? Your answer needs to have the correct number of significant figures.
