Question

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

Answer 1

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

Answer 2

the answer is C. -40 joules on plato, i got 100 on the test
