Question

Which of the following is true of an isobaric process

A. Temperature is constant.

B.Q = -u

C. Pressure is constant.

D. W = PV

Answer 1

Pressure is constant & W= PV

Step-by-step explanation:

If you lookat this picture.You can see that temperature is changed...that means internal energy is changed.And you can see pressure is 2atm always...

and also because the volume is incresed we can calculate the work using

W=p∆v

W=2atm*1m^3

So that equation is also true for this system.
