Questions
constant is the relation obeyed by a perfect gas during an adiabatic process, if the initial temperature of the gas is T, then what will be the final temperature of the gas when it is compressed to half of its initial volume.
detailed solution
Correct option is C
given PV3/2=Constant, for a perfect gas In adiabatic process relation between Pressure P and volume V is PVγ= Constant on comparing above two equations ⇒γ=3/2 given initial teperature T1=T final temperature T2=? initial volume is V1=V; final volume is V2=V2 In adiabatic process relation between temperature T and volume V is TVγ-1=Constant T1V1γ-1= T2V2γ-1 T1T2=V2V1γ-1 substituting the given values of T1,V1,V2 TT2=121/2 T2=21/2TTalk to our academic expert!

A gas is enclosed in a cylinder with a movable frictionless piston. Its initial thermodynamic state at pressure and volume changes to final state at in an adiabatic quasi-static process, such that 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 followed by an isochoric (is volumetric) process at volume. The amount of heat supplied to the system in the two-step process is approximately
