Which equation is correct for adiabatic process?

For such an adiabatic process, the modulus of elasticity (Young’s modulus) can be expressed as E = γP, where γ is the ratio of specific heats at constant pressure and at constant volume (γ = CpCv ) and P is the pressure of the gas.

Which is the valid equation for ideal gas?

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Can you use PV nRT for adiabatic?

In an adiabatic process, PVγ=constant. To find a relation between temperature and volume, we substitute P=NRT/V instead of pressure P.

Which of the following is applicable for an adiabatic expansion of an ideal gas?

W=−ΔU.

Is ideal gas equation valid for irreversible process?

Yes, it is not applicable for irreversible process. As we know in irreversible process there is no thermodynamic equilibrium during the process(but are in initial and final state) i.e. ideal gas eqn not valid during the process (but at initial and final state is valid).

Which of the following equation is correct for adiabatic process according to the first law of thermodynamics?

Concept: An adiabatic process is a thermodynamic process in which there is no exchange of heat between the system and surrounding, that is, the heat remains constant. Now according to the first law of thermodynamics ΔQ = ΔW +ΔU, so if ΔQ = 0.

Which is true for adiabatic process?

An adiabatic process is defined as a process in which no heat transfer takes place. This does not mean that the temperature is constant, but rather that no heat is transferred into or out from the system. (The actual definition of an isentropic process is an adiabatic, reversible process.)

What is the correct condition for the process to occur under adiabatic conditions?

For the process to occur under adiabatic conditions, the correct condition is q = 0. Explanation: A system is said to be under adiabatic conditions if there is no exchange of heat between the system and its surroundings. Hence, under adiabatic conditions, q = 0.
