That thing is used as a lever.
Can't find the options on the keyboard so ill try to describe it. I think either an He symbol or the greek letter alpha is accepted. There must be a 4 at the top left and a 2 at bottom left.
Augmentation or deduction of kinetic energy will tell you if any work is done here.
Explanation:
Here,
E<sub>k0</sub>=0.5mv<sub>0</sub><sup>2</sup>=16,537.5 J
E<sub>kf</sub>=0.5mv<sub>f</sub><sup>2</sup>=194,400 J
Now,
E<sub>k0</sub> - E<sub>kf</sub> = 177,862.5 J
Hence, work is done.
Have you understand, Shakira?
Don't forget to follow me if you have any other questions.
Explanation:
It is given that initially pressure of ideal gas is 4.00 atm and its temperature is 350 K. Let us assume that the final pressure is and final temperature is .
(a) We know that for a monoatomic gas, value of is \frac{5}{3}[/tex].
And, in case of adiabatic process,
= constant
also, PV = nRT
So, here = 350 K, , and
Hence,
= 267 K
Also, = 4.0 atm, , and
= 2.04 atm
Hence, for monoatomic gas final pressure is 2.04 atm and final temperature is 267 K.
(b) For diatomic gas, value of is \frac{7}{5}[/tex].
As, = constant
also, PV = nRT
= 350 K, , and
= 289 K
And, = 4.0 atm, , and
= 2.27 atm
Hence, for diatomic gas final pressure is 2.27 atm and final temperature is 289 K.
