Directions: The following question has four choices out of which ONLY ONE is correct.
A thermodynamical system is changed from state (`P^1, V^1`) to (`P^², V^²`) by two different processes, the quantity which will remain same is:

A thermo-dynamical system is changed from state (P_(1),V_(1)) to (P_(2),V_(2)) by two different process. The quantity which will remain same will be

A thermodynamic system goes from states (i) P_(1),V to 2P_(1),V (ii) P,V_(1) to P2 ,V_(1) . Then work done in the two cases is

A system changes from the state (P_(1),V_(1)) to (P_(2),V_(2)) as shown in the diagram. The work done by the system is

Of the following quantities , which one has the dimensions different from the remaining three?

Of the following quantities , which one has the dimensions different from the remaining three?

Of the following quantities , which one has the dimensions different from the remaining three?

Which of the following process is correct for given P-V diagram.

When a sample of ideal gas is changed from an initial state to a final state, various curves can be plotted for the process like P-V curve, V-T curve,P-T curve etc. For example, P-V curve for a fixed amount of an ideal gas at constant temperature is a rectangular hyperbola, V-T curve for a fixed amount of an ideal gas at constant volume is again a straight line. However, the shapes may vary if the constant parameters are also changed. Now, answer the following questions : Two moles of an ideal gas is changed from its initial state (16 atm, 6L) to final state (4 atm, 15L) in such a way that this change can be represented by a straight line in P-V curve.The maximum temperature attained by the gas during the above change is :(Take : R=1/12L atm K^(-1) "mol"^(-1) )

A thermodynamic system undergoes two process P_(1) and P_(2) from AtoB as shown in P-V diagram, choose the correct option.

Each question has four choices a, b, c, and d, out of which only one is correct. Each question contains STATEMENT 1 and STATEMENT 2. Both the statements are TRUE and statement 2 is the correct explanation of Statement 1. Both the statements are TRUE but Statement 2 is NOT the correct explanation of Statement 1. Statement 1 is TRUE and Statement 2 is FALSE. Statement 1 is FALSE and Statement 2 is TRUE. Statement 1: For events Aa n dB of sample space if P(A/B)geqP(A) , then P(B/A)geqP(B)dot Statement 2: P(A/B)=(P(AnnB))/(P(B)) , (P(B)!=0)dot
