One mole of a gas obeying the expantions...

One mole of a gas obeying the expantions P(V-b)=RT is made to expand from a state with `(P_(1), V_(1))` to a state with `(P_(2), V_(2))` along a process that by a straight line on a P-V diagram. Then the work given by:

A

`1/2 (P_(2)-V_(1)) (V_(2)+V_(1)+2b)`

B

`1/2 (P_(1)+P_(2)) (V_(2)-V_(1))`

C

`1/2 (P_(2)-P_(1)) (V_(2)-V_(1))`

D

`1/2 (P_(1)+P_(2)) (V_(2)-V_(1)+2b)`

Text Solution

Verified by Experts

The correct Answer is:
B

W=Area under the curve

An ideal monatomic gas is at P_(0), V_(0) . It is taken to final volume 2V_(0) when pressure is P_(0)//2 in a process which is straight line on P -V diagram. Then

One mole of an ideal gas is expanded from the state A(P_(0), V_(0)) to final state B having volume V. The process follows a path represented by a straight line on the P–V diagram (see figure). Up to what volume (V) the gas shall be expanded so that final temperature is half the maximum temperature during the process.

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

One mole of hydrogen, assumed to be ideal, is adiabatically expanded from its initial state (P_(1), V_(1), T_(1)) to the final state (P_(2), V_(2), T_(2)) . The decrease in the internal energy of the gas during this process will be given by

A gas with (c_(p))/(c_(V))=gamma goes from an intial state (p_(1), V_(1), T_(1)) to a final state (p_(2), V_(2), T_(2)) through an adiabatic process. The work done by the gas is

A system changes from the state (P_(1), V_(1)) to (P_(2) , V_(2)) as shown in the figure below. What is the work done by the system –

An ideal gas, in initial state 1 (P_(1), V_(1), T_(1)) is cooled to a state 3 (P_(3), V_(3), T_(3)) by a process which can be represented by a straight one on the P–V graph. The same gas in a different initial state 2 (P_(2), V_(2), T_(1)) is cooled to same final state 3 (P_(3), V_(3), T_(3)) by a process which can also be represented by a straight line on the same P–V graph. Q_(1) and Q_(2) are heat rejected by the gas in the two processes. Which is larger Q_(1) or Q_(2) . It is given that P_(1) gt P_(2).
