What work is done by a system on its environment when an ideal gas is maintained at a constant pressure of 200 newtons/meter2 during an isobaric process, while the volume decreases by 0.2 cubic meters?
A. 40 joules
B. 1,000 joules
C. -40 joules
D. -1,000 joules

Respuesta :

As we know that work done by external environment is given as

[tex]W = P\Delta V[/tex]

here we know that

P = 200 N/m^2

[tex]\Delta V = 0.2 m^3[/tex]

now we will have

[tex]W = P\Delta V[/tex]

[tex]W = 200 N/m^2 (0.2 m^3)[/tex]

[tex]W = 40 J[/tex]

so work done by external atmosphere will be 40 J

so correct answer will be

A. 40 joules
