Which of the following is true of an isobaric process

a. temperature is constant.

b. q = -u

c. pressure is constant.

d. w = pv

Pressure is constant & W= PV

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.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
