QAIPMT-2010-Ph-1978: NEET 2010 Physics - Class 11 AIPMT-2010-Ph-1978 Solution: If \(c_p\) and \(c_v\) denote the specific heats (per unit…

If cpc_p and cvc_v denote the specific heats (per unit mass) of an ideal gas of molecular weight M, then

Multiple Choice Options

  • A cp−cv=R/M2c_p-c_v=R/M^2
  • B cp−cv=Rc_p-c_v=R
  • C cp−cv=R/Mc_p-c_v=R/M
  • D cp−cv=MRc_p-c_v=MR

Step-by-Step Verified Solution

C v = molar specific heat of the ideal gas at constant volume C p = molar specific heat of the ideal gas at constant pressure, C p ' = MC p and C v � = MC v Also C p _ _ C v _ = R MC p � MC v = R C p � C v = R/M
