Thanks for your reply. I need more help from you. we say that internal energy is function of temperature only, but, when I was calculating air properties by an online property calculator, I noticed that internal energy changes with change in pressure, while keeping constant temperature as you...

I was confused that Cv is the heat needed to raise the temperature when volume is constant, so, Cv can only be used when volume is constant. But now I ve understood that to find out internal energy Cv is used regardless of any process, as, internal energy is the function of temperature only...
