Question

Molar gas constant is the same for all gases because at the same temperature and pressure, equal volumes of all gases have the
same
(A) number of molecules
(B)
ΚΕ.
(C)
density
(D) Ratio of specific heats​

Answer 1

Answer:

We know, R= nT/PV

assuming P,V and T to be constant.

Also we know, that equal volume of gases contain equal number of molecules, hence the value of R is also constant.

Answer 2

Answer:

D) Ratio of specific heats
