The molar heat capacity for an ideal gas

Options

  1. Ais zero for an adiabatic process
  2. Bis infinite for an isothermal process
  3. Cdepends only on the nature of the gas for a process in which either volume or pressure is constant
  4. Dis equal to the product of the molecular weight and specific heat capacity for any process

Correct answer

D. is equal to the product of the molecular weight and specific heat capacity for any process

Step-by-step solution

The molar heat capacity has the general definition C= 1 n Q T where n = number of moles, Q = heat absorbed by the gas and T = rise in temperature of gas. It is possible to obtain almost any set of values for Q and T by proper selection of a process.
