The above p-v diagram represents the thermodynamic cycle of an engine, operating with an ideal monoatomic gas. The amount of heat, extracted from the source in a single cycle is

A

`P_(0)V_(0)`

B

`((13)/(2))p_(0)v_(0)`

C

`((11)/(2))p_(0)v_(0)`

D

`4p_(0)v_(0)`

Text Solution

Verified by Experts

The correct Answer is:
B
`eta=(1-(T_(2))/(T_(1)))xx 100 implies (40)/(100) = 1-(T_(2))/(500) implies T_(2) = 300K` Again `(60)/(100) = 1-(300)/(T_(1)) implies T_(1) = 750K`
heat supplied =`nC_(v)(2T_(0) - T_(0)) + nC_(P)(4T_(0) -2T_(0)) = (n.3RT_(0))/(2) + (D5R)/(2)(2T_(0)) = (13)/(2)nRT_(0) = (13)/(2)P_(0)V_(0)`

Let barv,v_(rms) and v_p respectively denote the mean speed. Root mean square speed, and most probable speed of the molecules in an ideal monoatomic gas at absolute temperature T. The mass of a molecule is m. Then

In Fig., a container is shown to have a movable (without friction) piston on top. The container and the piston are all made of perfectly insulating material allowing no heat transfer between outside and inside the container. The container is divided into two compartments by a rigid partition made of a thermally conducting material that allows slow transfer of heat. the lower compartment of the container is filled with 2 moles of an ideal monoatomic gas at 700 K and the upper compartment is filled with 2 moles of an ideal diatomic gas at 400 K. the heat capacities per mole of an ideal monoatomic gas are C_(upsilon) = (3)/(2) R and C_(P) = (5)/(2) R , and those for an ideal diatomic gas are C_(upsilone) = (5)/(2) R and C_(P) = (7)/(2) R. Consider the partition to be rigidly fixed so that it does not move. when equilibrium is achieved, the final temperature of the gases will be
