Question

One mole of an ideal gas of =5/3 at temperature 400k is expanded adiabatically till its temperature drops to 200k. How much heat (in units of the gas constant r)sh

Answer 1

Answer:

incomplete question complete it

Answer 2

Answer:

300

Explanation:

How much heat (in units of the gas constant R ) should be supplied to it so as to restore the original temperature without changing the volume

further?

du = dq + pdv

since, dv = 0

dU=nR(T1−T2)/γ−1

    =1.R.(400-200)/5/3-1

    =300R
