0.09m cube of a fluid at 0.7bar are compressed reversibly to a pressure of 3.5bar according to law pvn=constant. the fluid is then heated reversibly at a constant volume until the pressure is 4bar, the specific volume is then 0.5mcube/kg a reversibly expansion according to a law pv2=constant restores the fluid to its initial state. compute the mess of the Fluid present, the value of n in the first process, and the networkdone on or by fluid in the cycle

Hi, my name is Julia, I'm 18.

Yesterday I broke up with a guy, I want to have fun.

If you are interested, write me here https://linktr.ee/julia.karandina

My nickname is julia_karandina

how is this a question? in order for me to answer it i have to understand the question

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
