Most Important Selected Qs for JEE AdvancedPhysicsThermodynamics

Paragraph: The dot in figure represents the initial state of a gas. An adiabatic divides the p - V diagram into regions 1 and 2 as shown. Question: For which of the following processes, the corresponding heat supplied to the system Q is positive

Options

  1. Athe gas moves up along the adiabatic,
  2. Bit moves down along the adiabatic,
  3. Cit moves to anywhere in region 1 ,
  4. Dit moves to anywhere in region 2 .

Correct answer

D. it moves to anywhere in region 2 .

Step-by-step solution

Above adiabatic graph heat has to be supplied. Since product of P ₀ ~V ₀ decreases so temperature will decrease.
