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.
For all antinodal positions we know that
now we also know the relation between phase difference and path difference
now we will have
now from above equation we will have
now for the first anti node position
N = 1
Option D is correct
