Question

7. A monatomic ideal gas undergoes a
thermodynamic process as shown in the figure
The molar specific heat of the process is
​

Answer 1

Answer:

molar specific heat capacity of monoatomic gas is 5/2 R

Explanation:

This is V v/s T graph and pressure i constant in this situation

so Cp = 2.5 R

Answer 2

Answer:

5R/2

Explanation:

by graph V vs T

(V)(T^-1) = const

(V^-1)(T) = const

comparing TV^n-1

n-1=-1

n=0

now plug n=0 in polytropic process formula

C=Cv+R/(1-n)

C=Cv+R

C= (3/2)R + R

C= 5R/2

SHORTCUT

by graph it's clear p is const

so C=Cp

C=5R/2
