In an isobaric process of an ideal gas, the ratio of heat supplied and work done by the system ( Q W ) is [ C _ P C _ V = ]

Options

  1. A1
  2. B-1
  3. C-1

Correct answer

C. -1

Step-by-step solution

In an isobaric process, pressure remains constant. The heat supplied to the gas is Q = nC_P T , while the work done by the system is W = P V = nR T . The ratio simplifies to Q W = C_P R . Using Mayer's relation C_P - C_V = R and the definition = C_P C_V , we obtain: Q W = - 1 Final answer: C
