Question

For N2 the value of Cp-Cv is equal to:

1) 14R
2)R/14
3)28R
4)R/28​

Answer 1

Answer:

Given, Cp-Cv= a for Hydrogen gas

Cp-Cv = b for Oxygen gas

relation between specific heat per unit mass:-

Cp-Cv=r

Cp-Cv= R/M

r= R/M

Here, M = molecular weight.

hydrogen gas :-

Cp-Cv = a

a = R/M

a = R/2

oxygen gas :-

Cp-Cv = b

b = R/M

b = R/32

ratio of a and b :-

a/b = (R/2)/(R/32)

=> 16

ratio of a and b = a = 16b

Answer 2

Step-by-step explanation:

N2 is a diatomic gass

we know Cp - Cv = r

r = R/M

M =28 mass of Dinitrogen

then Cp- Cv = R/28
