1.	15. Calculate the work done when a gas expands at a constant temperature from volume2 x 103m3 to 4 x 10-3m against a constant pressure of 1.2x 105 N m2
Answer» initially work done is 1200002000final work done is 120000.004now,so work done is 240000000-480 answer is 239999520 work done=pdVwork done=1.210^5(2000-0.004)=1.210^5(1999.996)=2399*10^5J

15. Calculate the work done when a gas expands at a constant temperature from volume2 x 103m3 to 4 x 10-3m against a constant pressure of 1.2x 105 N m2

Answer»

initially work done is 120000*2000final work done is 120000*.004now,so work done is 240000000-480 answer is 239999520

work done=pdVwork done=1.2*10^5(2000-0.004)=1.2*10^5(1999.996)=2399*10^5J
