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

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

Answer 2

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

Step-by-step explanation:

Given:

Ideal gas is maintained at a constant pressure
`P=200 (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 (N)/(m^(2))`

According to the formula,

work done
`\bold{W=P * d v}`

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

`=200 * -0.2`

`=40 \text { Joules }`

Result:

Work done done by a system W= -40 Joules
