Per NCERT eqn 5.13, the relationship between C_p and C_v for an ideal gas is which?
AC_p + C_v = R
BC_p × C_v = R
CC_p − C_v = R (per mole) — derived from ΔH = ΔU + Δ(pV) = ΔU + RΔT
DC_p = C_v
Answer & Solution
Correct answer: C. C_p − C_v = R (per mole) — derived from ΔH = ΔU + Δ(pV) = ΔU + RΔT
Per NCERT eqn 5.13, C_p − C_v = R for an ideal gas. Comes from ΔH = ΔU + RΔT per mole.
