Question

calculate the constant external pressure needed to compress an ideal gas from 25 dm³ to 15 dm³. the amount of work done in the compressor process is 3500 joules​

Answer 1

Answer:

the process is reversible as the pressure is constant means non spontanoues

therefore the pressure is negative

W=-P∆V

∆V=15-25=-10

W=3500 work done is positive as work done is done on system

3500=-p-(-10)

3500-10/1000=3.49 atm..

pressure is =-3.49

hope so helpful...
