Okay, I have this Extra Credit on my homework, and it's got me really confused. There are these charts where we have to calculate volume (v) and pressure (p). Let me type exactly what's on the paper.
"Using the formula P = V¹P¹/V², calculate the pressure needed to compress the given volume of gas. Complete the chart and graph your results. (V¹ = 4 L, P¹ = 1 kPa)"
Then there's a chart, let me try to type whats on it (it will look weird because I cannot type in chart form.)
Volumes: 3 L, 2 L, 1 L, .5 L, .25 L
Pressure: ?, ?, ?, ?, ?
Okay, all I want to know is how do you figure out those pressures? The worksheet says that that V¹ is 4 L, but then you have to use different volumes. Do I replace V¹ with whatever number they give me. Please help me understand!

I don't have a textbook oakster. But I think the other three have helped me out very much. Thank you.

NO! you have to replace V2 with given volumes:
P = (V1P1)/V2
P = (4 x 1)/3
P = 4/3
Now do the same thing for V2= 2. V2= 1 , V2= 5 and V2= 25

I think they want you to compress 4L of gas down to 3, 2, 1 etc. L. So you have V1 and P1, and the volumes in the chart are V2. Plug it into the formula and that's the answer. To graph, put V2 on the x axis and P2 (your answers) on the y axis. Make sense?

Those number just let you know what to work with. Replace V^2 with the new numbers that they give you. The equation that you now would work with is P=4*1*V. Plug in your numbers to that.

look in your textbook - there should be some form of help
