What work is done by a system on its environment when an ideal gas is maintained at a constant pressure of 200 newtons/meter2 du

Crank

Answer:

Work done done by a system on its environment is W=40 Joules

Explanation:

Given:

Ideal gas is maintained at a constant pressure $P=200 \frac{N}{m^{2}}$

Change in Volume $d v= -0.2 m^{3}$

To find:

Work done by a system during an Isobaric Process

Solution:

In a Isobaric Process, constant pressure is maintained, $P=200 \frac{N}{m^{2}}$

According to the formula,

work done $\bold{W=P \times d v}$

Substitute the values of pressure and change in volume in the above formula,

$=200 \times -0.2$

$=40 \text { Joules }$

Result:

Work done done by a system W= -40 Joules
