In thermodynamics, a process is called reversible when

In thermodynamics, a process is called reversible when

In thermodynamics, a process is called reversible when

According to the second law of thermodynamics, a process (reaction) is spontaneous, if during the process

Which one of the following equations does not correctly respresents the first law of thermodynamics for the given process?

For a given thermodynamic cyclic process, P-V indicator diagram is as shown in the figure. Process AB,BC & CA are isobaric, & isothermal respectively. Then which of the following curve represent correc V-T indicator diagram for the process ABCA ?

A gas is expanded form volume V_(0) to 2V_(0) under three different processes as shown in the figure . Process 1 is isobaric process process 2 is isothermal and and process 3 is adiabatic . Let DeltaU_(1),DeltaU_(2) and DeltaU_(3) be the change in internal energy of the gas in these three processes then

Why is the work done in isobaric process not zero always?

Assertion: Thermodynamics process in nature are irreversible. Reason: Dissipative effects cannot be eliminated.

By integration, make expressions of work done by gas in (a) Isobaric process (p=constant) (b) Isothermal process (pV=constant) (c) Adiabatic process ( PV^gamma= constant)
