Question
Why do we generally consider two specific heats for a gas?

Answer

  • A slight change in temperature causes considerable change in pressure as well as volume of the gas.
  • Therefore, two principal specific heats are defined for a gas viz., specific heat capacity at constant volume $(S_V)$ and specific heat capacity at constant pressure $(S_p)$.
