Question

In an adiabatic process,heat supplied to the system is zero.For a reversible adiabatic expansion of an ideal gas,the value or $\frac{dp}{p}$ is equal to :$(\gamma$= ratio of specific heats )

• A. $\gamma \frac{dV}{V}$
• B. $\frac{dV}{V}$
• C. $\frac{\gamma }{\lambda -1}\frac{dV}{V}$
• D. None of these

Answer 1

The correct option is A $\gamma \frac{dV}{V}$

An adiabatic process takes place without the transfer of heat or mass of a substance but this does not mean that the temperature is constant . It takes place between the system and its surroundings. In an adiabatic process, the energy gets transferred to the surroundings only as work. It is a process in which no heat is gained or lost by the system.
