The pressure of a gas is 100 kPa. If it is compressed from 1m3 to 10 dm3, find the work done.

A.990 J

B.9990 J

C.9900 J

D.99000J✓ Correct

Explanation

Given, Pressure, 5 P 100kPa 10 Pa Initial Volume, 3 1 V 1m Final Volume, 3 3 2 3 2 V 10 10 m 10 m x 5 2 w P V W 10 (1 10 ) 99000J >> Thus, the correct option is (d) 99000 J
