Question

The work done during the expansion of a gas from a volume of4dm3 to 6 dm^{ 3}$ against a constant external pressure of 3 atm is :-

Answer 1

Answer : The work done during the expansion of a gas is .

Solution : Given,

Initial volume of gas =                  

Final volume of gas =

Pressure of gas = 3 atm

Formula used :

where,

W = work done of a gas

P = pressure of a gas

= final volume of a gas

= initial volume of a gas

Now put all the given values in above formula, we get the work done of a gas.

Therefore, the work done during the expansion of a gas is
