Question

Question 7 1 pts Calculate the work done on the system when 2.0 mol of an ideal, monatomic gas is compressed reversibly and isothermally from 2.0L to 0.5 Lat 298 K. Express answer in Joules (J). 15,000 0 -6900) 6900 150

Answer 1

Answer -6900J

We have work done= -PdV

Also we have PV= NRT

Therefore P= NRT/V

Therefore Work done = -NRT ln (V2/V1)

here N=2 mole

T=298k

R=8.314 J/K-mol

Putting down the values we have

Work done = -2*8.314*298*ln((0.5/2))

=6900J
