Question

A quantity of gas in a piston cylinder has a volume of 0.374 m3 and a pressure of 200 Pa. The piston compresses the gas to 0.110 m3 in an isothermal (constant-temperature) process. What is the final pressure of the gas?

Answer 1

Answer 2

P1V1 = P2V2
Where P1 and V1 are your initial pressure and volume

P2 and V2 are the final

Plug in the appropriate quantities and solve for P2

Answer 3

it's 680 i may have another one

Answer 4

A cylinder of gas at room temperature (20°C) has a pressure p1. To what temperature in degrees Celsius would the temperature have to be increased for the pressure to be 2.7p1?

Answer 5

P1/T1 = P2/T2

However you must convert Celsius to Kelvin for this to work

Answer 6

so i have 293 k but what do I do with it

Answer 7

293K is your T1

You have P1 and P2

Plug in, solve for T2

Answer 8

okay so I see the 2.7 and I have the 293 what would the first pressure be the 1?

Answer 9

Plug in p1 as the first pressure
Plug in 2.7p1 as the second pressure

p1 will cancel out and you’ll be left with temperature only

Answer 10

I figured it out and it's 518
