Change Physcis Physics homework Piston produced Volume

In summary, the student is trying to solve a physics homework problem, but is having difficulty converting units. They have figured out that the area of the piston is 1x10^-16m^2 and the distance is 1700nm. They then convert these units to SI and solve for the change in volume, which is 1.7x10^13m^2. They next ask how to calculate the work done by the gas molecules, but are unsure of the equation.

Sounds like some sort of nano-machine.

<h2>1. How do I calculate the change in volume produced by a piston?</h2><p>To calculate the change in volume produced by a piston, you will need to know the initial volume of the cylinder, the final volume of the cylinder, and the area of the piston. The formula for calculating change in volume is change in volume = final volume - initial volume.</p><h2>2. What is the formula for calculating the area of a piston?</h2><p>The formula for calculating the area of a piston is area = π x (diameter/2)^2, where π is the mathematical constant pi and the diameter is the distance across the piston.</p><h2>3. How do I measure the initial and final volumes of a cylinder?</h2><p>The initial and final volumes of a cylinder can be measured using a graduated cylinder or by calculating the volume using the cylinder's dimensions. To measure using a graduated cylinder, fill the cylinder with water and record the initial volume. Then, add the piston and record the final volume. To calculate using dimensions, use the formula for volume of a cylinder: V = π x (radius)^2 x height.</p><h2>4. Can I calculate the change in volume without knowing the area of the piston?</h2><p>No, the area of the piston is a necessary component in calculating the change in volume produced by a piston. Without the area, you will not have all the necessary information to use the formula: change in volume = final volume - initial volume.</p><h2>5. What units should I use when calculating the change in volume produced by a piston?</h2><p>The units used for calculating the change in volume produced by a piston will depend on the units used for the initial and final volumes and the area of the piston.
