Options

A. P-4,Q-3,R-2,S-1
B. P-2,Q-1,R-3,S-4
C. P-4,Q-3,R-2,S-1
D. P-2,Q-4,R-3,S-1

Answer

A

Explanation

`(P) to (4)`, Whenever internal energy of a system decreases then the temperature always decreases.
In an adiabatic expansion work is done by the gas.
`rArr` w is `-ve`
`rArr DeltaE =-ve`
`rArr` temperature decreases
`(Q) to (3)`, For an ideal gas `((dE)/(dV))_(t)=0`
`(R) to (2)`, Whenever internal energy increases temperature of the system increases.
`(S) to (1)`, During resonance `DeltaH_("combustion experimental")` is less than `DeltaH_("combustion calculated")`
Similarly, `DeltaH_("combustion experimental") lt DeltaH_("combustion calculated")` in `CH_(2) -CH=CH_(2)` where resonance takes place.
