A gas take part in two thermal processes...

A gas take part in two thermal processes in which it is heated from the same initial state to the same final temperature. The processes are shown on the `P-V` diagram by straight lines `1 rarr 3 ` and `1 rarr 2`

A

`W_(13)gt W_(12)`

B

`W_(12)gt W_(13)`

C

`W_(13)= W_(12)`

D

None of above

Text Solution

Verified by Experts

The correct Answer is:
A
Since the temperature remains constant,
`Delta T=0`
Now
`W_(12)=(1)/(2) (P_(1)+P_(2))(V_(2)-V_(1))`
`W_(13)=(1)/(2) ( P_(1)+P_(3))(V_(3)-V_(1))`
`W_(12)-W_(13)=(1)/(2)[P_(1)(V_(2)-V_(3))+(P_(3)-P_(1))]lt0`
`W_(13)gtW_(12), Q_(13)gtQ_(12)`

A gas takes part in two processes in which it is heated from the same initial state 1 to the same final temperature. The processes are shown on the p-V diagram by the straight lines 1-3 and 1-2. 2 and 3 are the points on the same isothermal curve. Q_1 and Q_2 are the heat transfer along the two processes. Then,

A gas took part in three thermal processes in which it is heated from the same initial state to the same final temperature. The process are shown in the P-V diagram by straight lines 1-2 , 1-3 and 1-4 . Q_(1) , Q_(2) and Q_(3) are amount of heat supplied to the gas in the process 1 to 2 , 1 to 3 , 1 to 4 . respectively.

An ideal gas takes part in two thermal process in which it is heated from same initial state A. Once it is taken from A to B and in the other case from A to C. The points B and C lie on an isotherm. Choose the correct options.

A gas is enclosed in a cylinder with a movable frictionless piston. Its initial thermodynamic state at pressure P_i=10^5 Pa and volume V_i=10^-3m^3 changes to a final state at P_f=(1//32)xx10^5Pa and V_f=8xx10^-3m^3 in an adiabatic quasi-static process, such that P^3V^3=constant. Consider another thermodynamic process that brings the system form the same initial state to the same final state in two steps: an isobaric expansion at P_i followed by an isochoric (isovolumetric ) process at volume V_r. The amount of heat supplied to the system i the two-step process is approximately

An insulting container of volume 2V_(0) is divided in two equal parts by a diathermic (conducting) fixed piston. The left part contains one mole of monoatomic ideal gas whereas right part contains two moles of the same gas. Initial pressue on each side is P_(0) . The system is left for sufficient time so that a steady state is reached. Find (a) the work done by the gas in the left part during the process, (b) initial temperature in the two sides, (c) the final common temperature reached by the gases, (d) the heat given to the gas in the right part and (e) the increase in the internal energy of the gas in the left part.

The internal energy of a certain substance is given by the following equation : U=3 PV+84 where U is given in kJ/kg, P is in kPa, and V is in m^3//kg A system composed of 3 kg of this substance expands from an initial pressure of 400 kPa and a volume of A 0.2 m^3 to a final pressure 100 kPa in a process in which pressure and volume are related by PV^2 =constant. In another process the same system expands according to the same pressure-volume relationship as in above question, but from the same initial state of the final state as in above question, but the heat transfer in this case is +30 kJ.Then the work transfer for this process is :
